I'm leaning more towards that actually not being OCD; it seems, ... different. Maybe impulse issues are a big part of your problems, however. I had impulse issues when I was younger, I think. It's worth seeing someone, so you can get more control and stability - also, hitting, slapping, and pinching people isn't especially friendly, so should be seen to, in my opinion. I have had pretty severe OCD, for basically as long as I can remember, with various kinds of manifestations, and I honestly just cannot get that "OCD" vibe, from your initial post. The thing that strikes me the most, is impulse issues, but, the thoughts do, however, wave an OCD flag. Due to the other stuff, I'm just not convinced OCD is so likely. Anywho, get yourself an appointment with someone and get a diagnosis, plus some support, ... is pretty much my contribution to this thread.
