Do I have some sort of compulsive disorder or something?

I have had acne for many years. Since I was like in 6th grade up until now, and I'm turning 23 this April. I can never not pick on my acne, pimples, or blackheads. I find it hard to not touch my face at all. I don't think I can go a month without at least picking on one pimple. My sister used to pick on her pimples too, but stopped many years ago, and she started taking better care of her skin and her face is clearer now than when she was younger. Do you think I may have some sort of compulsive disorder?
