Count me as among those on the spectrum. I was evaluated as having tendencies that lean towards aspergers, but not enough to properly place me there. Funnily enough, it's not in the DSM anymore - it's a perfectly cromulent term IMO. I even went to a school designed to facilitate learning for people like me for a little while (I was in my last year there when I registered here).
DrCrow, Danfun, know that I will probably never truly empathize with the degree of your issues as I am pretty high-functioning. However, I will also support you as much as possible here and certainly attempt to be more understanding of certain annoyances.
Sarcasm can be the bane of my existence as well, even though I love it. What generally hurts me the most is my lack of social awareness. I do tend to go on tangents in conversations, and sometimes even have difficulty focusing when discussing something important to others if it's not immediately pressing to me. Then I get anxious and often internally freak out for a few minutes, quieting down or (if I'm lucky) making sure I can get away from everyone without having a pity party. It sucks and I imagine you two can relate on that one.
I, too, have trouble with change. My parents are selling my childhood home, and I've been in denial. It's only now when I go home and see all the boxes piled up that I realize this is actually happening.
