Hi. my friend cuts herself but she never tries to hide it (never wears long sleeve shirts) and so i dont know whats going on. she has all these cuts on her left arm which look pretty new and faded ones on her right arm.. and she even carved a star on to her left wrist.. i dont know if she's doing this because shes depressed or just because she likes it.. shes always so happy and stuff.. so i dont know. should i talk to her about it? thanks!
