Hi and Welcome,
I am glad you found us. I feel that it is not so much as quitting self injuring as it is learning not to self injure. So I second and third ozzie and emily's advice. Getting help through the counselors at school is useful because they are more able to get to the bottom of the issues that lie under the surface of self injury. Coming here is wonderful as well because the people here have been through it, they have had successes and failures and truely understand how difficult it is to stop this habit. They are able to draw from their success to give good advice to help you through the day and they can draw on their failures to provide the empathy that the rest of the world lacks toward this problem. We are working toward getting better together and I am glad you are here to help us along as we help you.
Take care and welcome once again,
Carrie
