I was actually coming to this forum to write your very post. I have been so anxious lately and one of the ways it manifests is in the dermatillomania (also 'air hunger'-feeling like I can't breathe). The Picking is out of control right now. I am actually in pain. I do it when I am trying to go to sleep or relax. I can go YEARS without doing this, now I can't stop. I am on Wellbutrin and it helped for a long, long time.
