I have done it on my chest, stomach, hips, thighs, knees, feet, fingers, hands, wrists, elbows and shoulders. but mostly on my shoulders, wrists and thighs.
I would like to believe that I have stopped with it, but sometimes I find myself wishing for it Yes I know it's bad, and that's why I'm fighting it.
Unfortunally I have a new but "better" habbit I have developed while Im trying not to cut. Instead of cutting, I beat myself. Sometimes with a metal candlestick or other hard or heavy objects, but especially objects with sharp edges or tips. So now I have bruises all over my body instead of cuts. But it isn't as good as the other and it's hard not to give in.
