I am 43 and was given my official DX last week. I had other issues (PTSD) and (DID) and had been in therapy 4 years for that. My therapist was busy treating the trauma issues and did not have a chance to address this aspect. So I went to an expert and had myself checked in order to rule it out... or in as the case was.
My mom has read some links I sent her and she said "You were just like that as a kid! I just thought you were super smart and the social problems were the other kids fault." I told her she was not wrong.

Anyway, finally understanding this is the reason I am the way I am allows me to accept myself for the first time in my life. And I can now stop blaming myself for being so different from the other people I know.
