I did it for a short while in my life, when my frustration and anger, and confusion about whether it is my mental health or bad relationships was at it’s peak. I decided it is bad relationships I suffer, and I am pretty ok. I stopped doing anything to hurt myself now. It’s been six months. During that time, I was diagnosed borderline traits, probably because of that SH. It was only a short-lived means of coping after extreme stress and exasperation! I never did it before (35 years old) and I don’t do it anymore in my early 50’s.
