Dermatillomania, means I pick at my skin obsessively which had lead to the scarring that is probably on my scalp and back (and also counts as SH). The scar by my eye is from getting bit in the face by a small dog when I was little. The one on my upper left thigh is from getting jabbed with a sharp ahh pencil forever ago (it's still coloured like the pencil lead in that one tiny spot where the tip pierced through the skin ToT)
