skin picking

I am new to this. I thought I was the only one in the world who "picked my skin" It's constantly on my mind and whenever I am in front of a mirror(no matter where I am at) I will pick!! It is literally ruining my life! I work as a waitress and it is very embarrassing going into work with all facial scars(due to my obsessive picking) and red marks all over my face. It is very reassuring to know that I am not the only person with this. Does anyone on here have any advice to give me? My husband keeps telling me"just stop!" but I can't he doesn't understand why.
