There's other ways to relieve the pain y'know.

I started cutting again recently myself and at one point did it so deep I passed out (not sure if from the sight or loss of so much blood) and pretty much vowed to never do it again.

Don't you have other means of keeping you busy?
I sometimes scratch myself instead of cutting, weird but it doesn't leave marks and it can be just as painful.

Do you know what's causing the urges? Or just depression?

I'm glad you're going to your doctor though, that's really brave because I never would D:

I saw these jar things filled with glitter once, apparently they're meant to help? I'm not sure you may have to google it D:

You're welcome, always here if you need a chat

My advice, if your going to do it, keep it clean, clean whatever you use first, and try and keep the cut clean as well

You need to try to find some interests that will keep you busy, hang out with friends, play a game, listen music.. anything you like to do.

And ive read something about the butterfly project too, maybe you know this?, draw a butterfly on wherever you cut and name it to comeone you care about so you dont want to cut the person you care about. something like that.. you can always google that too ofcourse.

And well your getting help already you said, so just try to keep talking about whatever triggers you to do that to yourself and meanwhile try to keep yourself busy.

Hope it will work out for you
