I usually stick to a box cutter, but i never cut too deep just so i dont have any noticeable scars, just deep enough to draw a mild amount of blood and cause me pain; I also cut across my skin slowly to increase the pain of it, to make up for not cutting deep. Other times i use fire, just put my skin above the flam until i cant handle it, or burn cigarettes on my skin. For strangulation i use this one thin scarf that i have, tie it around the part thats just under my jawline were the veins are and pull both sides as hard as i can for as long as i can; usually until my grip starts to losen from being so light headed. Another method i used to do was bang my head against a table during class, but i stopped doing that because i got in a lot of trouble when my head ended bleeding from how hard i was doing it. (But i wouldent recomend that one because it could cause brain damage.) A lot of the time I starve myself, although the pain in my stomach has gotten easier to deal with. I also bite the skin around my fingers off. It hurts a lot when its in the more sensitive spots.
