Sort of know where your coming from. I start self injury back in high school. I use to have anxiety issues. The though of having to go to high school scared me. The worst times for me were the nights before big tests and, the first and only prom I every attended. That time required stitches. For me it servered as a slap in the face to calm me down. Thankfully i managed to stop si once I graduated. Every now and againt, I still feel the need to though.
