Please help me, what should i do?!

Honestly, it is not worth it. It may be an easy way to take out anger, but go for a walk or do something else instead. There are also alot of negative sides to cutting:
-You can't wear short sleeves
-If you cut a vein you could easily die
-It stings like a b**** for the next few days
-And if somebody sees, they will send you to therapy causing everything to be worse.

I used to cut too.

go to the doctor and ask them to recommend you for therapy, so you can start to challenge these thoughts about damaging yourself.

these thoughts about harming yourself stem from deep rooted issues which you need to tackle with an expert

why do u want to cut yourself thats bad ur loossing blood!!!! DON`T!
are u mad or something
