Depressed friend. what do I do?

Wow that is awful! I'm sorry your experiencing this. I went through a period of depression and I really didn't have many friends and I think during that period, friends were what I really wanted. Maybe talk with her parents and see if they plan something fun to do? Or maybe you two should get together and do something she's always wanted to do. School counslers are really hard to talk to as well, they don't seem to understand. Maybe find another counsler?
