I was diagnosed by a clinical psychologist after being on the waiting list for years.
I knew I had ADHD, I did suspect Autism too so I didn’t think either would have come as a shock.
However I feel weirdly blindsided by the autism one. More awkward and embarrassed about it.
I’ve told people I have a diagnosis of ADHD, but I just don’t feel comfortable telling anyone about the autism one. I don’t know why exactly. I guess because autism is seen in a slightly different way to ADHD. More severe maybe - not my perception necessarily, but society.
