I have been suffering with the symptons for a long time. I've dropped out of school twice and now I'm in med school. I've failed in almost every class last semester because I couldn't cope with the feelings and I've tried suicide twice. Also I've had problems with substance (prescripted and illegal) abuse but never got addicted, just been trying to calm down my feelings.
This semester my parents moved in with me, because they've noticed I lost a lot of weight and that I wasn't having a satisfying academic life.
But still, I have been drowing with negative feelings and I honestly feel like I can't graduate. But I also can't quit because I'll be fucked up with student loans and can't afford it if I don't graduate. 
I have a very strong social anxiety and can't make friend in the uni, from another places and internet I have a lot of friend whose I hang out every weekend but they can't really fill me up and I'm constantly feeling like I'm a burden to them.
Anyone else been there? And how to deal with it? How can I cope with things to study and graduate? I really want to be a doctor so I can help people and I feel like it's part of trying to channel all of my sensibility into something good. But I don't feel like I'm capable of.
