I'm a 25 year old man yet I can't stop cutting myself
Why do you think you cut yourself?
It's calming, it is like meditation. I don't feel pain in my body when do it.
Cutting yourself is very dangerous. You need to talk to a professional to stop this behavior.
I don't need any help, I'm fine with it. It works for me.
It is not good to keep up this habit. You can hurt yourself badly like this and scar your body significantly. There is nothing wrong with looking for help when you need it.
