fear of hurting other people?

Sometimes I have a fear of hurting someone with a knife. Sometimes the target of attack can be someone with whom I feel very close to an love very much.

The imaged do distress me because I would like to have dinner with someone whom I value very much, without having intrusive 'knife' thoughts entering my mind. The bad thoughts do disappear when I am more relaxed with the person or people that I happen to be eating with.

Thank God other people go through this. I remember such terrible thoughts I've had. I've never told a doctor because the images usually involve my Wife and Children and I would never hurt them they're my best friends. I was always afraid the doctor would take my kids from me. It's funny that everybody mentions OCD I use to have these really strange habits of drumming my fingers in patterns for long periods of time and I would make math patterns from the numbers on the clock. I haven't done these things in years but I still do little things like flip the remote in my hand smack my head with the things (not hard just tapping) I also use to be really bad with picking at my skin literally I would spend an hour plus looking on my arms for pimples.
