scalp picking is hard to stop!!

I guess I'll start from the beginning... I was abused emotionally and physically by my mother (a "Mommie Dearest" if anyone is familiar) and sexually abused by one of her many boyfriends. I really liked the info about picking from suppressed rage (I had/have a lot towards my mother). I started abusing alcohol and drugs at age 13, but went to rehab and have been sober for over 2 years (I'm 33 now). I think drugs and alcohol numbed the pain from childhood - then I had to deal with a lot of healing with positive coping skills. I am now a wife and a mother of two beautiful children. And mostly very happy. But the continuous scalp picking....I finally told my husband. He says to stop..."just stop" he says....I WOULD IF I COULD... Oh my...it's been really gross! Just a couple of weeks ago I had a huge cyst toward my hair line/forehead. I found pleasure from picking it, letting the blood dry, and picking it more. I enjoy smelling my fingers with the blood on them (I can't believe I'm writing this...) Who does that? Us, I suppose. I just don't get it...I could give up drugs and alcohol (not that easy...but I did) and now I can't stop picking at my scalp. I think my hair is thinning out because of it. I have certain spots on my head where I know I can find something to pick at. I'm breastfeeding my newest daughter. When she wakes at night for some, I will stay awake and pick at my scalp until there's nothing left but a really sore head. I'm trying to stay "pick free" just for today...one day at a time, you know? It's so incredibly difficult! I've read "habit reversal training" can work...here's some info http://en.wikipedia.org/wiki/Habit_reversal_training Thank you to all who can relate and who can sympathize and empathize...this too can pass..
