Brought to tears when finding this site.

I can't even explain if it's joy, or sadness after realizing it's real. I've always known I had a "problem" with extreme skin picking, but I thought I was alone or just crazy. My family would notice the picking and horrible scars on my body and scream at me to stop ... as if it was just that easy. I didn't know it had a name or there was anyone else, until I found this site tonight. I have been picking at every inch of my skin since I was 7 yrs old. Primarily at my arms, face, legs and recently my chest/breasts. I am now 27 and my whole body is scarred and disformed from head to toe. I am so ashamed of what I have done that I wear long sleeves and pants in the hundred degree summer weather to cover it up. I know what I'm doing is wrong , I know it's going to hurt and scar later, but I can't overcome the crazy urge to pick. I often do it without even noticing. I literally start picking and get lost in it for hours EVERY DAY, almost like a black out, not even noticing 3 hours has gone by and I am still standing in front of the mirror ... picking. It's ruining my life. I am starting to develop hermit like behavior because I don't want to leave the house because I am so ashamed of what I've done, or that some one will see it. A woman at my work saw my full arm on accident today, she told me it looked like I had a severe case of chicken pox or leprosy ... it brought me to tears, which lead me to finally realize I need help. Please help me ... what medications, behavioral rememdies, creams, lotions etc have worked for anyone in this situation? Where did you even begin to start fixing this? I am so desperate for answers...
