I'm curious about how old you were, the first time you remember having a thought along the lines of 'I wonder if I might be autistic'?
And when did you know you were?
7 years for me, from 30-37.

@EverAutistic 2 years ago (age 31) I started psychotherapy and also started to do more research to understand my childhood ADHD diagnosis. I came across the birdsites #ActuallyAutistic and #ADHD bubble. And suddenly I could relate to so much of it! Made a online test and brought it into therapy. Luckily my therapist offered to do the screening. I only had like 2 or 3 month between first thought and diagnosis. Still, took (and still takes) me a lot time to accept and not feel like an imposter.

That's so brilliant that you could be assessed by someone who already knew you well. My autism assessor brought up the possibility of ADHD for me too. Reading AuDHD experiences on the birdsite have made me more and more convinced. I don't have the energy or money to go through another assessment any time soon though.
The imposter syndrome is such a struggle. Needs banishing!
