I Used to Self Harm

I can't control myself when there's a huge surge of negative emotions. First time, I did it was when I was 17 and my abusive father accused of something I didn't do and he punished me for it even though he knew I didn't do it. Then I hit my fits on the wall so hard it bruised when I was in college and felt so lonely. Again around same time, when my ex dumped me for another girl. Recently, I did it because I was disappointed with my weight.
