Still Depressed

I am still very lonely and still very depressed. I take medication daily and it doesn't help. I mean some very rare days I have good days but they're mostly terrible. I don't know for sure what would make me happy. I know for sure that I think constantly about suicide. I've already attempted it 3 times. I've talked to therapists. I don't think switching meds is really going to make a difference. I've done electroshock therapy. I'm just sick and tired of being sick and tired. I sleep too much. I need friends, but who would want to be friends with me...im miserable. i start school soon in a couple of weeks. hopefully that will help brighten my day and maybe i can meet some new people. i just want out!!!!!!!
