My life is falling apart?

I've gone through several bereavements and treatment for long-standing severe depression. Now, the shock has gone and I've stopped treatment and medication and my life seems to be in utter freefall. My finals are coming up so soon and I can't focus. My family relationships are falling apart, I'm in too much debt, can't find a job. I honestly don't know whether I can go through with it all. I'm on a good grade but I don't know if I can physically get through the next few weeks to get my degree. I'm scared of falling into a deep depression afterwards if I'm unemployed. It feels like we have no chance.
