Imposter Syndrome: A Real Problem, Even If It’s Not a Diagnosis

Imposter syndrome isn’t listed in manuals like the ICD-10 or DSM-5, and it’s not something the NHS formally treats. But that doesn’t mean it isn’t real, or that it isn’t worth taking seriously.

Like low self-esteem, perfectionism, and chronic self-doubt, imposter syndrome may not be a diagnosable disorder, but it can still take a real toll on your mental health, your relationships, and your career.

What Is Imposter Syndrome?

The term “imposter phenomenon” was first described in 1978 by psychologists Pauline Clance and Suzanne Imes. They noticed that many high-achieving women doubted their accomplishments despite clear evidence of success. Since then, decades of research have shown that imposter syndrome affects men and women alike across professions, from medicine, academia, and business to law, tech, and the arts.

At its core, imposter syndrome is the persistent belief that you’re not as capable, competent, or qualified as others think you are, despite ongoing evidence of your skills and achievements. It’s that gnawing worry that you’ve somehow fooled everyone, and it’s only a matter of time before you’re exposed.

You might notice it in how you think, feel, or behave:

• A fear of being “found out” as not good enough

• Dismissing your successes as luck, timing, or mistake

• Constant pressure to prove yourself or avoid mistakes

• Holding back from opportunities in case you fail or fall short

• Feeling like you’re one step away from being exposed as a fraud

Researchers have also identified different “imposter types.” For example:

• The Perfectionist: anything short of flawless feels like failure.

• The Expert: never feeling knowledgeable enough.

• The Soloist: believing you must succeed alone, without help.

• The Natural Genius: struggling if things don’t come easily.

• The Superperson: pushing to excel in every area, all the time.

These aren’t rigid categories, but they highlight the different ways imposter feelings can show up.

Why Isn’t Imposter Syndrome a Diagnosis?

There are a few reasons why imposter syndrome isn’t classified as a mental health disorder:

• It often overlaps with anxiety, depression, or low self-worth.

• It tends to be situation-specific, surfacing at points of transition, visibility, or responsibility.

• It’s more about how we relate to our thoughts and feelings than a broader mental illness.

Imposter syndrome is especially likely to flare up in high-pressure environments. for example, starting a new job, stepping into leadership, giving a presentation, or being evaluated. These contexts can amplify self-doubt even in people with an impressive track record.

But just because it doesn’t have a clinical label doesn’t mean it’s not causing suffering or shaping your choices in ways that keep you stuck.

The Impact Is Real

Imposter syndrome doesn’t just stay in your head. It affects how you feel about yourself, how you show up, and how you navigate challenges. Left unchecked, it can lead to:

• Overworking to prove yourself or avoid being caught out

• Playing small or staying quiet to avoid the risk of failure

• Difficulty enjoying or acknowledging your achievements

• Constant overthinking, self-criticism, and low confidence

• Avoiding growth or change even when it’s something you want

Many of the strategies we use to manage these feelings like perfectionism, procrastination, or pushing through silently can make things worse in the long run.

You Don’t Need a Diagnosis to Get Support

Therapy isn’t just for people with a diagnosis. One of the most useful questions you can ask is:

Is this getting in the way of how I want to live?

If your imposter feelings are affecting your wellbeing, your performance, or your confidence in day-to-day life, that’s reason enough to seek support.

Therapy for imposter syndrome can help you:

• Understand what’s driving your imposter feelings

• Spot the patterns that keep them going

• Change the way you relate to doubt, fear, and high expectations

• Build confidence and self-trust from the inside out

Different approaches can be useful depending on your situation. For example:

• CBT can help address unhelpful thinking patterns.

• ACT teaches skills to respond more flexibly to self-doubt.

• CFT builds a more compassionate and supportive inner voice.

• EMDR helps process past experiences and triggers that fuel self-criticism.

You don’t have to keep battling these thoughts alone or waiting until things get worse.

Common Questions About Imposter Syndrome

Is imposter syndrome the same as anxiety or low self-esteem?
Not exactly. While they overlap, imposter syndrome is specifically about doubting your competence despite clear evidence of ability. You can feel confident in some areas of life and still experience imposter feelings in others.

Who experiences imposter syndrome?
Research shows it’s widespread. Students, professionals, leaders, creatives, and parents can all experience it especially during transitions, promotions, or times of increased responsibility.

Can therapy really help with imposter syndrome?
Yes. Evidence-based therapies can help you understand the cycle, respond differently to self-doubt, and develop the confidence to pursue opportunities without being held back by fear of being “found out.”

The Takeaway

Imposter syndrome might not be a formal diagnosis but that doesn’t make it any less real. If it’s holding you back or making life harder than it needs to be, it’s valid and it’s worth working on.

Imposter syndrome isn’t a sign you’re broken. It’s a sign your mind is trying (in its own way) to protect you. With the right support, you can learn to step out of that cycle and build confidence that lasts.
