I do it often without even realizing I'm doing it until I'm bleeding. A hair brushes my face, I scratch the itch, find a bump and scrape it off too. I try to keep myself from doing it by exfoliating daily. Less bumps=less picking for me. My right cheek is horribly scarred right now from a bad case of milia over the winter. And of course once the cyst is out, then there's the scab that I pick off....I feel you. I stopped cutting but actually have more scars from the unconscious picking.
