I have done all of those, and I never want to again. Please, if not for you for the people around you, don't cut, or bruise, or anything like that. I started cutting and it was hard for me to stop, I kept telling myself the same things, and I kept doing it. My mom found out one day because she made me take my hoodie off and saw my arms. We talked awhile, and I won't say I stopped then, I continued on my legs until she found out again. That was when I stopped cutting. My mom helped me and I stopped. Now, several months later, you can hardly see my scars, because I never had the nerve to cut deep. I used a couple of methods to stop, drawing lines in red pen on my arms was one of them, and another was putting ice on my skin. Though later, when I started this school year I started getting mad and frustrated and made my arms bruise from punching them instead of other people, I just stopped that quickly, since I was just doing the same thing as before. The point is, never cut, find someone to help you if you don't have the self-control, though be careful what you say to counselors, if they get the hint you will hurt yourself again they can get you committed. Try the pen or ice methods too, if it will help for a while.
