Argh! Depression sucks...Last year I was diagnosed with clinical depression and I am living proof things do get better. I was in an awful state and it seems I can relate to how your friend feels. I'm still on anti depressants and they've helped me but they don't always help for everyone. I felt it was nice to have some sympathy but not loads of cooing over and wrapped in a piece of cotton wool for the rest of my life. I took one step at a time. I left school, I got hold of my feelings and I've been working my ass off since. I guess its different for diff people but I was a total wreck and yes I tried to kill myself - when I was 9!! And I'm better. I know I'm not much help, but try and have faith. And don't worry too much, it only makes you feel worse
