Tell someone. That is not good - wrists are for bracelets not for cutting
My friend cuts herself and is eventually going to kill herself. She's not my best friend or anything, but she sits beside me in class and writes poems about death. I don't know what to do?
Tell that although you may not be close, you're there for him/her and tell them how they've greatly impacted you
Maybe you should tell someone. Life is precious, no matter what she thinks of hers. Tell her that things will get better eventually, that she needs to give herself another chance. Hope this helps. :(
