Why do people with ADHD feel they don’t deserve success?
Many people with ADHD describe a persistent feeling that their achievements are accidental, unearned, or undeserved. Evidence from NHS, NICE and peer-reviewed research shows this pattern is closely tied to emotional regulation difficulties, lifelong negative feedback, and the impact of rejection sensitivity.
Emotional patterns can fuel self-doubt
According to clinical summaries, emotional dysregulation, executive challenges, and rejection sensitivity can lead to internalised shame and chronic self-doubt. This often results in the belief that success is accidental or that personal strengths don’t “count” (Simply Psychology).
Repeated setbacks shape a negative self-story
NICE NG87 highlights that people with ADHD often face ongoing setbacks; from school struggles to social difficulties and inconsistent performance. These experiences can reinforce the idea that success is not genuinely earned, especially when negative feedback becomes internalised over many years (NICE NG87).
Underachievement and comparison create a belief of unworthiness
Research shows that chronic underachievement, peer comparison, and trauma from criticism increase the likelihood of discounting achievements or expecting failure. Many individuals begin to minimise their efforts, assuming their positive outcomes are luck rather than skill (NIH).
Imposter syndrome is especially common in ADHD
Imposter syndrome appears at higher rates in adults with ADHD, often tied to perfectionism, rejection sensitivity, masking, and long-standing feelings of “never living up to potential.” These factors make achievements feel fraudulent, even when they are genuinely earned (ADHD Centre).
Reframing success supports healthier self-belief
UK ADHD charities emphasise that strength-based identity work, self-compassion, and deliberately acknowledging effort help break cycles of self-criticism. These approaches support a more accurate and grounded understanding of success and personal capability (ADHD Foundation).
A brief note on assessment and support
If feelings of unworthiness or imposter syndrome are affecting confidence or wellbeing, a structured ADHD assessment may help clarify patterns and guide support. Services like ADHD Certify offer ADHD assessments for adults and children in the UK.
Takeaway
People with ADHD may feel undeserving of success because of emotional sensitivity, lifelong criticism, and internalised self-doubt, not because their achievements lack merit. With the right support and reframing strategies, it’s possible to rebuild a healthier, more confident sense of success.
