I am the same, im ashamed to undress because I pick my skin so badly on my chest and my legs, it started for me as part of my skin condition, my skin bubbles up and it hurts sooo much, (im on meds for it now) but I would scratch and my doctors didnt blame me for it, but the scratching meant i broke my skin, i had holes, and scars, when i got put onto the meds, i didnt stop scratching, i pick, and pick, always got an infected spot somewhere, what i try and do is the moment i catch myself doing it, atm im trying to force a less hurtful urge, so everytime i go to pick or catch myself doing it, i start tapping the place instead, sometimes it helps sometimes not so much...
