I'm new here...this has been going on too long. I need help :(

Hey guys. I just want to say how thankful I am to have found this site for the first time today. Second- thank you guys so much for being so honest, helpful, and encouraging to eachother- I have so much admiration for that! I'd never spoken to anyone about this problem-but I am sure people notice. I have been too ashamed to ever seek help because I felt so alone. Every day, I pick at my face. My cheeks and chin get it the worst-I even cut bangs so people couldn't see what I had done to my forehead. It has affected my life-especially socially- for 6 years now. I don't know how to stop. At the time, I don't even think about it being a big deal...but as soon as I stop, I'm in tears. I hate what I'm doing to myself. I have had a dream of pursuing a music career and this has affected me to the point where I get anxious to even be seen by anyone. So because of this, I stay at home-which puts me in front of the mirror for another round of this horrible cycle. I have seen a lot of success stories on here-and many talking about a challenge. How do I start this? Where do I start? I know it's going to be a battle-because every day I tell myself that I had done it for the last time. I just know I want this to end-none of us deserve what we do to ourselves!
