I have been in therapy for 7 years. 3-4 years ago, I started to SI but never cutting at first.
It wasn't until my therapist warned me to stay away from sharp objects that I started to think about it. I was horrified before to think of doing that. then, the curiousity got to me. Why do people cut, what relief does it bring them. Unfortunately, I proceeded to find out. Now I do it occasionally.

I feel like if my Therapist hadn't mentioned it way back when, I wouldn't have gone down this road. Can therapy be dangerous, influencing someone to do something destructive?
I hate to think of it like this. Therapy is difficult, but should ultimately serve to protect you. I would never bring this up to my T, I wouldn't want him to feel bad about it.
He was only trying to help.
