Need to stop... now.

Hello, I'm new here. I've had a problem with skin picking since I was 6 years old... I remember the very first time. I was overwhelmed with school and felt very anxious. I've had other problems in my life, had a turbulent childhood and home life, lots of trauma and stress... picking greatly eased my inner turmoil; it was something ELSE I could focus on. I'm deeply, deeply ashamed of it and have only kinda sorta told some people. It was primarily focused on my upper arms and shoulders... I have lots of tiny little scars there now. I'm 24 now. SOMEHOW I found the resolve to stop it... for a while. I got over so many of my other problems and was determined to stop, and I did. It was at least a year, maybe 2 that I didn't or very rarely did. Then I had stress with my job, my significant other... and it started in full force again. It migrated in my attempt to not pick at my ARMS (now it's my lower back, neck, jaw, and face... which is SOOOO much worse!!!). I'd sit in front of a mirror telling myself to stop... tell myself "this will be the last time" blah blah blah... and it's been a whole year of this and it's gotten out of control. So here I am, trying to find that resolve again and stop for good. I don't want to destroy my face, and I have to stop now before I do even more damage. I hope that maybe talking about it here, putting my determination out there into words might help me a little.
