punishing my face

I think perfectionism may be a root cause of my picking. I think when I pick at my face I am punishing it in a way. I also get a weird satisfaction from the sting I feel when using toner after picking. Does anyone else do this? It's like, "Take that face! That's what you get for not being smooth and poreless!" I also find myself laughing at this picking issue I have, but the truth is, I want to stop and can't. I hate my skin for not looking better. I also pick unconsciously sometimes. I scratch at dry skin, be it on my face, back, scalp... I pull at split ends... What can I do, particularly in public to keep from these behaviors? Anything worked for anyone? I always worry that people are looking at my picking away and going, wow she's weird.
