too scarred, can't stop

Hey everyone, I'm new to this site. I've been picking for 4 years. I've really never had bad acne but I've made it into a problem by picking at even the slightest sign of a blemish. I pick because I'm nervous or anxious or even when I'm bored. I've tried to give myself something to keep bussy when I want to pick like knitting or running but so far nothing has worked. No matter what I do I always seem to turn back to the big lighted mirror and ruin whatever little progress I've made. Eventhough I know I'll feel like crap afterwards I can't seem to stop myself. This addiction has caused problems with my family and with my self esteem. I know even if I finally stopped now I'll probably be left with permenant scarring on my face. I feel hopeless. It is comforting to know I'm not the only one suffering from this problem. Please let me know of anything that has been helpful to you. At this point i'm willing to try anything. Thank you.
