I'm 43 and freshly labelled with Asperger's just two months ago after being "undiagnosed in childhood and misdiagnosed in adulthood" to quote Liane Willey (Pretending To Be Normal). A few teachers noticed something different about me when I did things like memorizing the first 2,000 digits of pi, but if they ever said anything about it to my parents, I never heard about it. And since we moved around a lot, there was never enough continuity with teachers or counselors for them to see patterns or do anything about it.
Like lae (Mon May 15, 2006 7:58 am) I'm glad my parents didn't know (or chose to ignore) my differences, since they probably would have put me in an institution. I'm pretty sure my father was an Aspie; he eventually killed himself after years of trouble getting along with people at work (which, I suspect, is why we moved so much).
Now I've been having "people problems" at work, always with shallow, codependent gossipy types who attack people they can't understand. They were so cruel to me in my last workplace that I had to leave wonderful friends and fulfilling volunteer work to transfer to a job 1,000 miles away. After a few years of being treated here for post-traumatic stress disorder, I'm finally getting back to the point where I can try to get a life. Which is what led me to research Asperger's and get a professional evaluation.
I've always been high-functioning enough to pass for normal 90% of the time, until someone pushes my buttons emotionally, or I get stuck in an over-stimulating environment. But in a way, that makes it harder for me, because people think I "look" normal and then are shocked when I react in a way that makes them wonder if I'm crazy. I think this is especially difficult for women, since American culture has strong traditional expectations for us to be outgoing, codependent, caretaker types. That's why my diagnosis as an Aspie has been so empowering; now I don't have to feel guilty or inadequate for being introverted and independent.
