Unfortunately, this is my main form of SH. I started out hitting my arms, but the bruises were too obvious. Then, I started hitting my head within the hairline. No one can see that.

When hitting isn't enough, I've been known to scratch shapes into my skin with a fingernail file or a blunted knife. Tonight, I laid outside in the snow until the cold was beyond painful.

You are not alone. I wish I could say the socially acceptable crap: "don't do it, you are worth more than that, etc etc," but I'd be such a hypocrite for saying it when I do the same thing.

Just know that you truly are NOT alone. Do not be afraid to ask for help first, if you are in a position to be able. I know there are many of us here who would be glad to listen and validate your emotions.

Hitting has been my main form of self harming as well. The first time I self harmed I hit myself until I had a huge bruise. That was in middle school. My friend at school saw it and I told him what happened and he looked at me like I was crazy. That was the first time I realized that SH is not healthy. You are not alone. Hang in there!
