out of control

My picking has gone completely out of control the past couple months. I thought I was doing better. Now my breasts, right arm and back are covered in sores and scabs. I'm so embarrassed. I can sometimes see people looking at me weirdly when they catch a glance at my arm especially. It has about twenty sores on it now and each breast has about 5 large scabs on them. I pick them at night until I can fall asleep. Sometimes in the middle of the day at work I get an urge to pick at them in the bathroom. I don't think I'm under any stress but I could be in denial, I guess. Does anyone else pick their breasts?
