I've been a skin picker/hair plucker for at least seven years. I've completely destroyed the skin on my arms and midsection, to the point where I don't even like doctors seeing it. There aren't many doctors/therapists who understand trich and obsessive compulsive skin picking disorder. Seems like there isn't much help for us. Meds do sort of lower the urge to pick and pull, but the scars never go away and neither do the imperfections we pick at.

Here are a couple of websites that might help you...

Hope you feel better soon.
