"Stop Hurting Yourself"

I think it means to stop phisicaly hurting yourself and that you don't have to be cool by stupid things. And that your body is very important. It doesn't feel good anymore after you get it all out of your system. It just makes you look stupid. And it also means to stop mentaly hurting yourself. You can really hurt your self-esteem. And you can also hurt yourself by getting addicted to it. And after that its too late.
