Impostor Syndrome: Why You Feel Like a Fraud (Even Though You're Good at What You Do)
Have you ever achieved something you worked really hard for, only to find yourself wondering whether you actually deserved it?
Perhaps you've left a corporate career, teaching or the NHS, taken a completely different direction, retrained and started your own business. You have years of experience, skills you've put blood, sweat and tears to develop and plenty of evidence that you're good at what you do...
Yet somehow, when it comes to backing yourself, you start to doubt everything.
Thoughts race through your mind like:
'Who am I to do this?'
'What if I'm not as good as everyone thinks I am?'
'There are so many other people doing this. Why would anyone choose me?'
Or perhaps you're still in your profession but despite your experience, qualifications and achievements, you worry that one day someone will realise you're not as capable as they thought.
Maybe you find yourself overthinking decisions, comparing yourself to others, downplaying your achievements or feeling as though you need to work twice as hard to 'prove yourself.'
You might even put off opportunities because you don't feel ready, telling yourself you need 'just a little more' experience, another qualification or a bit more confidence first.
And if you're running your own business that self-doubt can creep into everything - from setting your prices and promoting your service to wondering whether you're qualified enough to charge for your expertise.
If any of this sounds familiar, you might be experiencing impostor phenomenon, or what is commonly known as Impostor Syndrome.
Impostor Syndrome is the experience of doubting your abilities, struggling to recognise your achievements and fearing that you'll be exposed as less competent than other people believe you to be.
And here's the frustrating part: you can have all of the qualifications, experience, the positive feedback and all of the evidence to show that you're perfectly capable, yet still feel as though you're somehow winging it.
As a Clinical Hypnotherapist, I often work with people whose anxiety sits alongside perfectionism, overthinking and the relentless need to get things right.
From the outside, they appear capable, organised and successful. But internally, they're questioning themselves, anticipating mistakes and putting enormous pressure on themselves to keep everything together.
So why can it be so difficult to believe in yourself, even when there's plenty of evidence to support you?
In this post today, I'll explain what's happening in your brain, why Impostor Syndrome can become such a persistent patten and how you can develop a more balanced relationship with yourself.
What Does Impostor Syndrome Actually Feel Like?
Impostor Syndrome isn't simply a lack of confidence. It's the gap between what you've achieved and what you believe about yourself.
You might recognise some of these experiences:
You struggle to accept compliments - someone tells you you've done a great job, and rather than taking it in, you dismiss it, downplay your contribution or assume that they're just being nice.
You attribute your success to luck - you passed the exam because the questions were easy. You got the job because the other candidates weren't as good and they've settled for you. You business is doing well because you've been fortunate.
You worry about being found out - even when you're competent, you feel as though you need to prove yourself repeatedly to avoid being exposed as someone who doesn't really know what they're doing.
You set impossibly high standards - getting something right isn't enough. You need to be absolutely right - preferably the first time - without asking for help or making a mistake.
You over-prepare and overthink - you spend hours checking your work, rehearsing conversations, researching every possibility or mentally going over something you said/did days ago.
You find it hard to switch off - resting feels uncomfortable because there's always something else you could be doing to prove that you're capable, productive or worthy of your position.
You compare yourself to everyone else - you see other people's confidence, achievements and polished social media posts, then use them as evidence that you're somehow falling behind.
You can put yourself off opportunities - you worry that you won't be good enough so don't speak up in meetings, struggle to charge what you're worth or feel anxious about taking on more responsibility.
Some of these patterns may also sound familiar if you experience high-functioning anxiety or perfectionism. You might appear to have everything under control while privately overthinking, worrying about getting things wrong and putting yourself under enormous pressure. (I've explored this further in my blog post: The Hidden Struggle Behind High-Functioning Anxiety.)
And when something goes wrong? It becomes confirmation of everything that you've suspected about yourself and you go hard on beating yourself up for those failures.
Yet when something does go well, it somehow doesn't count...
It's an exhausting way to live because the goalposts keep moving. No matter how much you achieve, your brain finds a reason why you haven't quite proved yourself yet.
Why Do You Feel Like An Impostor Even When You're Successful?
The term 'impostor phenomenon' was introduced in 1978 by psychologists Pauline Clance and Suzanne Imes.
Their work described high-achieving women who continued to feel intellectually fraudulent despite clear evidence of their abilities and accomplishments. They explored how family experiences and social expectations could contribute to these beliefs.
Although the original research focused on women, impostor feelings aren't exclusive to women. People of different genders, ages and backgrounds can experience them, particularly in situations where they feel under pressure to perform or prove themselves.
Importantly, Impostor Syndrome isn't a formal mental health diagnosis. It's a term used to describe a recognisable pattern of thoughts, feelings and behaviours, which can overlay with anxiety, low self-esteem and perfectionism.
And while there isn't one single cause, understanding how the brain processes perceived threats, mistakes and feedback helps explain why these feelings can be difficult to shake.
Your Brain is Designed to Notice Potential Threats
Your brain has a VERY important job: helping you navigate your environment and respond to things that might put you at risk.
To do that, it constantly processes information, looks for patterns and makes predictions about what might happen next.
The amygdala is one part of the brain involved in detecting and responding to emotionally significant information, including potential threats. It works alongside other brain regions involved in attention, memory, decision-making and regulating emotional responses.
When you're feeling anxious, your attention can become more focused on information that signals a threat. If you're worried about being judged or making a mistake, you may find yourself scanning for signs that something has gone wrong.
And that threat doesn't have to be physical. It might be the possibility of making a mistake at work, disappointing someone, being criticised or appearing incompetent in front of your colleagues or clients.
Your brain can treat these situations as significant because of what they might mean to you: rejection, embarrassment, failure or losing the respect for others.
Imagine you've been asked to lead an important project.
Instead of thinking that they've asked you because they trust in your abilities, your mind jumps straight to:
'What if I mess this up?'
'What if they realise I'm not as experienced enough?'
'What if I can't answer a question?'
We play through hundreds of 'what if' scenarios (they always tend to be the negative, worse-case ones to!)
What you're doing here is negatively forecasting and anticipating problems before anything has actually gone wrong.
But in doing this, anxiety kicks in.
This is because your brain finds it challenging to distinguish between a real threat or an imagined one.
So your body responds with a racing heart, muscle tension, a churning stomach or that familiar feeling of being on high alert. (For more interesting ways that anxiety affects the body check out my blog post here.)
You then interpret those anxious feelings as evidence that something is wrong. Your mind might tell you, 'I'm this nervous because I'm not ready' when the anxiety may actually reflect how much pressure you're putting on yourself.
Feeling anxious doesn't automatically mean you're incapable. Your body's response to a situation isn't a reliable measure of how well you'll handle the situation.
When this response becomes a familiar pattern, even positive opportunities can trigger anxiety rather than excitement.
Your Brain Pays More Attention To Mistakes Than Achievements
Have you ever completed a project or a piece of work successfully, only to spend the evening obsessing over one small thing you have could have done better?
Or received ten positive comments and one piece of constructive criticism, then replayed that single criticism in your head for the next three days?
I know this one well from my own experience as a teacher. I always had outstanding lesson observations but one small improvement point and that's all I would hyperfocus on.
Criticism can feel particularly difficult when you're already questioning your abilities. A single comment can start to feel like proof that you're not good enough, even when there's plenty of positive feedback to suggest otherwise. (I explored why we can react so strongly to criticism, and how to respond to it differently in my blog Why Criticism Hurts.)
Our brains don't process every piece of information in a perfectly balanced way.
Attention and memory are influenced by our emotional state, expectations and previous experiences. When we're anxious, we can become more alert to criticism and mistakes, while finding it harder to give positive feedback the same weight.
This is often described in psychology as negative information-processing biases.
For someone experiencing Impostor Syndrome, it might look like this:
You deliver a presentation and it goes well. There's plenty of engagement, people respond positively and you receive lovely feedback.
But one person asks a difficult question that you struggle to answer.
You manage to get there in the end, but guess which part you keep replaying the rest of the day?
You got it!
Rather than remembering the presentation as an overall success, you focus on the question you couldn't answer. You might even begin to question whether the positive feedback was genuine and think about what everyone really thinks of you.
When this becomes a repeated pattern, you can end up with a very one-sided view of your abilities. You're not necessarily doing badly; you're giving one of the things that went wrong far more attention than the things that went well.
I'm not suggesting that you ignore mistakes or dismiss constructive feedback. We can genuinely learn from these experiences. The aim is to evaluate them more fairly, rather than allowing one difficult moment to outweigh everything else.
Perfectionism Keeps You Trapped in the Impostor Cycle
Perfectionism and Impostor Syndrome often go hand in hand.
You might believe that if you work hard enough, prepare enough or check everything carefully enough, you can prove your worth and prevent anyone from questioning your abilities.
So you put in extra hours. You double-check (or quadruple-check) the email. You rehearse what you're going to say. You can't possibly say no even though your to do list is long enough already. dare say. So you take on more responsibility than you have time for because saying no might make you look incapable.
And temporarily, this can feel reassuring.
You finish the task. Nothing goes wrong. You receive positive feedback. FANTASTIC!
The feeling of achievement might be great in the moment but it's short-lived as the negative introspection creeps in. Instead of recognising that you were capable of doing the job, you come up with an excuse for it.
The next time a challenge comes along you feel you need to do even more and this creates a self-reinforcing cycle:
You can end up working incredibly hard but still feel increasingly uncertain about yourself.
And the more you rely on perfectionism to manage your anxiety, the harder it can become to tolerate uncertainty, delegate tasks, ask for help or accept that doing something well is enough.
The important thing to highlight is that high standards aren't necessarily a problem. Wanting to do a good job can be strength.
It's when your standards become tied to your sense of worth, or when anything less than perfect feels like evidence of personal failure - that's when the pressure becomes exhausting.
Research supports the link between impostor feelings and perfectionistic tendencies. A 2025 meta-analysis by Hills and Gotwals found that impostor feelings were more strongly associated with concerns about making mistakes and how other judge you than with simply striving for high standards.
In other words, wanting to do well isn't necessarily the problem. Feeling that you must be perfect or risk being exposed as inadequate, is a different experience.
Your Brain Learns From What You Repeatedly Think and Do
Here's where neuroplasticity comes in.
(Neuroplasticity refers to the brain's ability to change it's structure and function in response to experience, learning and repeated activity.)
Your brain is constantly adapting. The way you think, behave and respond emotionally can become more familiar through repetition.
If you regularly respond to challenges by telling yourself you're not good enough, your attention naturally begins searching for evidence to support that belief.
If you repeatedly avoid situations that make you feel anxious, you may miss opportunities to discover that you can cope with them.
And if you consistently dismiss compliments, you lose opportunities to practise accepting positive feedback.
I am not saying that it's always as simple as thinking your way out of it. These patterns don't develop overnight, but over many years and they are influenced by your experiences, relationships, environment and circumstances.
But what I am saying is that your current patterns aren't necessarily permanent.
Consider what happens when you learn a new skill, such as driving.
Initially, it requires conscious effort and attention. You're sitting upright, gripping the steering wheel at ten and two, and consciously thinking about every move. With practise, aspects of driving become more familiar and automatic.
Emotional and behaviour responses are more complex than learning a straightforward skill, but the broader principle is relevant: what feels automatic today isn't necessarily how you have to respond forever.
You can begin to practise responding to challenges differently, noticing your achievements more accurately and allowing yourself to experience uncertainty without treating it as proof that you're failing.
Why Reassurance Doesn't Always Make Impostor Syndrome Go Away
You might think that the answer is simply to gather more evidence of your abilities.
More qualifications, more experience, more positive feedback or another achievement to add to the list.
But if you're experiencing Impostor Syndrome, you can achieve all of these things and still doubt yourself.
You get the promotion, but tell yourself you were lucky.
A client praises your work, but you assume they're just being nice.
You successfully launch your business but focus on what you haven't achieved yet.
The problem isn't necessarily a lack of evidence. It's how you interpret it.
Psychologists call one relevant thinking pattern confirmation bias. This is the tendency to notice or interpret information in ways that fit what we already believe.
When you believe you're not good enough, you pay more attention to mistakes and dismiss the things that show you're capable. This keeps the self-doubt narrative going - even when your experiences suggest otherwise.
Try asking yourself: Would I judge someone else as harshly for doing the same thing?
If a colleague made the same mistake, would you decide they were incompetent? If your friend or daughter started a business, would you assume they didn't deserve their success?
Probably not.
Learning to recognise when you're applying a harsher standard to yourself is a useful first step towards breaking the cycle of self-doubt.
How to Start Managing Impostor Syndrome
You don't have to wait until you feel completely confident before you start doing things that matter to you.
Confidence often develops through experience, rather than arriving in advance as a magical feeling that gives you permission to begin.
Here are a few ways to start challenging the patterns that keep Impostor Syndrome going:
Notice what went well
At the end of the day, take a moment to identify what went well, what you handled effectively or what you learned. It doesn't have to be a huge achievement!
Perhaps you spoke up in a meeting, asked for help instead of struggling alone, completed something you had been putting off or handled a particularly difficult conversation calmly.
The point isn't to convince yourself that everything is wonderful. It's to give your brain a more balanced account of your experiences, including the things you might usually overlook.
Separate facts from assumptions
When you catch yourself thinking, 'I'm going to be found out,' pause and ask yourself what evidence supports that prediction.
What do you actually know? What are you assuming?
You don't have to prove that everything will go perfectly. You simply need to recognise that your anxious prediction is not the same as a fact.
Practise doing things without being perfect
You might allow yourself to send an email after one careful check instead of reading it ten times. You might contribute an idea without rehearsing every possible response.
These small changes can help you discover that you don't need to eliminate every possible mistake before you take action.
Pay attention to the way you speak to yourself
Notice the language you use when you make a mistake. Do you tell yourself, 'I got that wrong,' or does your mind immediately jump to: 'I'm useless!'
The first describes what happened. The latter turns it into a judgement about who you are.
Learning to distinguish between the two can help you respond to setbacks more constructively.
Stop measuring yourself against everyone else
You rarely have access to the full picture of another person's life, abilities, worries or experiences.
You see their achievements, not necessarily the preparation, uncertainty or mistakes that came before them.
Use other people's success as a source of learning or inspiration when it helps you, rather than evidence that you're falling short.
And remember that you can be learning something new and still be competent in what you already do.
I Know I Shouldn't Be So Hard on Myself But...
The tips above can help you to start challenging self-doubt, but they all rely on conscious effort. When anxiety peaks, it can be much harder to think rationally, step back from the negative thoughts and access a more balanced perspective.
You might know that you're capable, recognise that you're being too hard in yourself and understand that making mistakes doesn't mean you're a failure. Yet when the pressure kicks in those familiar thoughts can take over anyway.
This is where Solution Focused Hypnotherapy can help, by supporting you to manage anxiety, building on your existing strengths and practise responding to challenges differently.
How Solution Focused Hypnotherapy Can Help With Impostor Syndrome
Solution Focused Hypnotherapy combines forward-looking talk therapy with hypnosis to help you manage anxiety, develop more helpful thinking patterns and focus on the changes you want to make.
Rather than spending sessions repeatedly analysing what's wrong, we focus on what you would like to be different and build on the strengths you already have.
This might include:
Reducing anxiety and overthinking so you can approach challenges without getting caught up in every possible way that things could go wrong.
Managing perfectionism, helping you feel more comfortable making mistakes and asking for help, and accepting that doing something well doesn't mean doing it perfectly.
Building confidence and self-trust by recognising your achievements and developing a more balanced view of your abilities.
Moving forward despite self-doubt so you can take opportunities, make decisions and put yourself out there without waiting to feel completely ready.
Hypnosis provides an opportunity to practise relaxation and mentally rehearse responding to situations differently.
The aim isn't to eliminate every doubtful thought or convince you that you'll never make a mistake (we are human after all!). It's to help you respond to challenges with less anxiety, greater perspective and more confidence in your ability to cope.
You don't have to wait until you feel completely confident to start believing in what you're capable of.
