Found out you’re autistic, ADHD or both as an adult? You’re far from alone.
Why so late?
Many AuDHD adults grew up before autism and ADHD could be diagnosed together. Masking, “bright but lazy” school reports and traits hiding each other meant many were missed.
You weren’t slow to notice. The system was slow to look.
Many adults only find out they are autistic, ADHD or both after years of feeling different without knowing why. Awareness used to be much lower, and the picture people had in mind was narrow. Children who were quiet, bright or good at masking were often missed. Some were treated for anxiety or low mood instead. Finding out later can bring huge relief, because your life finally makes sense. It can also bring grief for the support you did not get.
How it can feel
Put next to each other, the difference is clear:
| Relief | Grief |
|---|---|
| “So that’s why!” | For years without support |
| Words for your experience | For the person you tried to be |
| Finding your community | For the struggles nobody saw |
| Permission to rest | For a childhood you can’t redo |
Both are valid, and they often arrive together.
Signs you might have been missed
Everyone is different, but these come up again and again:
- “Bright but lazy” on every school report
- Always exhausted after socialising
- Coping at work, falling apart at home
- Diagnosed with anxiety or depression first
- Relating to AuDHD posts a little too much
Getting assessed (UK)
- Start with your GP: Ask about autism and ADHD assessments.
- Write it down: Examples from childhood to now.
- Know your options: In England, Right to Choose may cut waits.
- Bring someone: A parent or partner can add history.
- Expect a wait: Community support helps meanwhile.
After diagnosis
- Go gently: Processing it all takes time.
- Learn your brain: Books, podcasts, AuDHD voices.
- Ask for adjustments: At work, study or the GP surgery.
- Find your people: Neurodivergent groups, online or local.
- Unlearn old labels: You were never lazy or too much.
Where to start
If you are wondering about yourself, start by writing down examples from across your life, including childhood. Take them to your GP and ask about assessment. Waits can be long, so look for community and information in the meantime. You do not need a diagnosis to start making life easier for yourself.
The bottom line
It’s never too late to understand yourself.
This post is for awareness, not diagnosis. Your GP is the best starting point if you’d like an assessment.
