I'm also wondering if I have Asperger's. I can relate to a lot of the things you posted, such as pacing and talking to yourself. When I was a child I would walk around in circles for hours making up stories in my head, but I would mutter them aloud, especially when people weren't around. However, I had no compunction about pacing when people were around, and just ignoring them. Finally, when I got old enough that I knew people would stop forgiving my behavior, I stopped. I still talk to myself a lot though!
