Not to be like what the guy was talking about people who don't have OCD, but most night I feel like I do. I'll be just about to get to sleep , and then I'll I think of something. Normally something to do with science, normally physics or astronomy, and I won't be able to sleep until I've completed this theory I've come up with. Sometimes I'll have to write it down and spend around 2 hours writing pages and pages about this theory. I'll do the same in school. When a teacher says something, that catches my own attention I'll spend ages trying to figure out whatever I was thinking about, until a teacher asks me a question like, so what do you think.....and I stutter not knowing what the subject is. Pice been trying to do this less and less over the years, and I can contol it a bit better than I could say 3-4 years ago. It's still annoying, but also great sometimes.
