Lynelle! First WELCOME too PC!!!!
I to have the urges when I come down. And I did some research on the need to want to do this. What I found is there is an increase of endorphins. They call it "runners high" I think that is where some of my addictive behavior has come from with cutting. I am recently trying too use exercise as a release, which for me is soooooooooooo difficult. What your saying makes alot of sense too me. I too have PTSD and have done things without knowing. It can be quite scary.
