any tips on how to stop cutting?

Keep yourself busy. When I'm not thinking about touching razors, I don't, it's all about distraction. Try listening to your favorite songs over and over again, find new ones, learn the lyrics and try to sing along, not for anyone but maybe just for you! Or find a really good book, hang out with positive people, take a run or if you're not into that go out and make new friends. Start a blog, and if you're seriously feeling bad, talk to someone you trust.

Tell someone you really trust and they can support you I have support from two people because I cut to and knowing I have the support makes me feel like I can stop and you have to believe in yourself

Keep your mind occupied long enough for you to talk to somebody professionally about it.

As difficult as it will be, one of the first steps is removing any items you use to cut with from the equation. It's how I stopped. Anytime I got an item and was ready to cut I made the decision to dump it. Throwing them away got easier and easier to do. And if you really start to get the urge to cut, Find someone to talk to. You don't have to tell them you want to cut just talk to them about anything that is interesting. Good luck to you, and remember, if you need someone to talk to, I'm here.
