As surely as there are downs, there will be ups. Life feels awful for you right now, as you are feeling trapped by your situation.
Take one step at the time. I think the first thing you need to do is find a job, so concentrate on that. There is nothing more depressing than having nothing to do.
There is no point in thinking about the money situation if there is nothing you can do right now.
As far as your family are concerned, maybe you need to take the first step. Sometimes after a crisis, people around you don't always know how to approach you. It may just be a matter of calling home and saying: mum/dad: I really need your support right now. But then, I don't know what kind of relationship you have with them.
I wish you all the best, and yes: things can only get better after what you have been through. You are stronger than you think.
