I am not a doctor, but it does sound like OCD. I have ocd, and while I don't have to touch things with my hands like that, I always have the feeling that something bad will happen to my family if I don't do certain things. These certain things are different all the time...just stuff that comes up. Alot of times, If I don't say I love you when hanging up the phone after talking to my mother, I will think something bad will happen to her. I would go to a doctor if you think its out of hand. I currently take Celexa and Luvox and they are both working very well for me.
Good Luck!!
