I agree that it's nice to read that I am not the only one with both AS and OCD, although I'm sorry that so many of you struggle. I had my first intrusive thoughts when I was about 8, and it was the worst in middle school, although now (especially since I went on Zoloft), it is very mild. But basically, every OCD symptom you read about, I have had to a certain extent at some point.
I'm glad for the people that can find the positive in it, but, like some of you, there are no good sides for me. It's weird, I've found "silver linings" in AS and ADHD (creativity, focus, etc.), but there doesn't seem to be any with OCD. (Although I do have a song stuck in my head constantly - apparently a symptom of OCD - that IS kind of funny. But mostly, OCD is crap.)
It's also interesting to read about the demonic possession - I would have intrusive thoughts that I would think were "sinful", and I would be afraid that, if I didn't do certain rituals, I would surely go to hell - and I'm not even really religious!
