after 10 years of skin picking, I've just understood that it's a disease.

I've been picking my skin since 10 years ago. I thought it was just a bad habit and I've never been able to stop it. I hope knowing about this problem can help me get over it. Is it really possible? at this moment I'm really ashamed of myself, my appearance and I'd rather stay at home all the time, not going to parties where every body shows off. is there anyone who really understands what I'm saying?
