I don't now, but years ago I did quite often, it is quite an addictive behavior to quit and one that many people do not understand, so I will explain why and how it worked for me. I used to cut myself when I was extremely upset and very emotional about something that pained my inner self. Cutting was a complete release of that emotional pain, it gave me something VISIBLE to cry over and somehow allowed the emotional pain to seep out with the blood. That is probably the best way I can explain it. I know it doesn;t make sense to most people, but if you are hurting so much on the inside and for some reason can not articulate the pain, cutting gives you permission to FEEL the pain.
