Unless you learn tp deal with what is driving you to cut, you will keep doing it. You need counselingand you will need to use the coping mechanisms they teach you.
How to relieve pain from cutting? I slipped up after being clean for a while... I'm fine though. I want to stop cutting. It really badly want to stop but I can't. Please, any other coping methods... :(
I searched with the phrase why people cut themselves and I got a lot of good links.
I read through a few and this one looks like it might help you---

If not, try the same search I did and look through the links.
Hang in there.
