I carved the word MAD into my thigh once. I regret it. It's mostly healed and that scar wasn't particularly deep so it didn't remain, and I'm glad it didn't.
I was where you are, cutting deeper and deeper.
It caused me some very bad scars, and I wish that I hadn't been so crazy as to do all that. Try whatever you can to distract yourself and get yourself through this time without cutting. Drink really cold liquids real fast and give yourself a brain freeze. Eat hot peppers. Hold ice in your hand until it freezes. Draw on yourself or paint on yourself. Try everything before you have to cut. And then try it again. You don't want the scars that I have, I promise you that.
