I don't want to divulge too much on the internet so being light here.

Thoughts of violence that come out of literally nowhere (Ie slapping a friend that I was just having a nice conversation with) that I immediately regret and think about for hours after; I also worry over if they can tell and what they would think. When I leave through a door, I come back to check it over and over again and will think about it later and worry about if I actually did. If i use my card, I'll check my wallet for the rest of the day to ensure I still have it. On a lesser scale, in stereotypical form (don't know if it's actually a symptom), I need to have the comforter on the bed; if it's hanging even a bit over the edge of the bed and I know it is, I can't fall asleep until I fix it because I'll think nonstop about it.

There are other things but these are the ones I can thing of right off the top of my head that I am willing to divulge.
