Yeah, when I was 14 about twice. I didn't get into it. But yes I listened to Linkin Park and kids on teen open diary talked about it so I tried to do it but I don't mind admitting my teenage misery was very typical and silly. People who do it a lot talk about it feeling good, but it didn't feel good to me.
I had a few friends who cut themselves a lot. I think it serves as a coping mechanism when you are young and in pain and out of control of your life.
i think i only did it on purpose once. but that was during science class when we needed a blood sample to view through a microscope. i wonder if that would even be allowed today. we didn't wear gloves or anything.
