I know what you mean by cutting and reopening wounds as when i cut i did that too. I have such bad scars from it and not like you i heal horribly. It can take a few weeks for just a tiny scratch on me to heal. When i was cutting i at the time got a tattoo and it also gave me that feeling which is now why i have 16 of them and well i also have 11 peircings (8in each ear, nose lip and tongue though i dont wear my nose and lip rings anymore ever since i stopped cutting) all of my peircings i did myself too except for my tongue and i did all my tattoos as well. I made my own tattoo gun so it was easy at the time to keep shooting them. I also did tattoos onother people for some timebut dont anymore. Im glad you responded to the post. I hope you can find something other than cutting to relieve whats going on. Big hugs to you and if you ever need someone to talk with im always around.
