I tried to not cut, so now I bang the back of my head. Oddly, I think to myself it is not causing any damage because I always wake up the next day feeling the same as the day before. I have noticed my vision is going south though. Oh well. Not much in life I want to see anyway. ha ha.

I only do this while at work and in stress. It is getting to where I am doing it harder and harder. Before it was just like thumping it. But about 30 min ago when really stressed it was full force and I felt the blackout thing start but then was still here so didn't pass out.

Has anyone else been through this form of SI? How in the heck did you stop doing it? There is always a wall and there is always my big stupid head!!
