I actually haz OCD, and I am so glad that it's just a mild case.
Example, when I'm at school, I try as hard as possible not to touch bathroom doors, I even use the paper-towel door opening thing. If there's no paper towels, I maneuver myself so that I can get the door open w/o my skin touching it.
Also, whenever I see something nasty I constantly wipe my mouth. It's as if I don't the nasty thing is on my mouth.
I used to have a problem with socks, if they didn't feel exactly right on my foot I would cast them off and become upset and angry. Same thing with shoes, if they didn't work right, time to start over.
Right now, it's my laptop. I get a little bit... myeeeh, if it's not clean around the mouse-pad area.
