What kind of alternatives are there?

Okay. I have been cutting myself for about 2 years now. I never did it on my arm, but on my hips and the insides of my legs, so that no one would see them. However, last night, my twin brother saw the tip of one of them over my jeans and wouldn't leave me alone until I showed him the rest of my hip, telling me that if I had nothing to hide, it shouldn't be a problem. When I finally showed him, he freaked out. He cried and was begging me to stop. Ordinarily, I wouldn't care what other people ask me, but my brother means the world to me and I feel terrible about hurting. What kind of alternatives are there to cutting? I've tried to stop before, but never succeeded. Now, I have to. I can't go on making my brother feel this way.
