Very sorry to hear that. I think you have short-term, medium-term, and long-term planning to do. In the short-term, you need a lousy job - whatever you can get. What steps can you take towards applying for such a dead-end job? What skills do you have for low level jobs?

In the long term, you probably need to finish college. The amount of debt you already have is irrelevant - you cannot do anything about it, unless you are so disabled that you get an SSDI and in that case your student loans will be forgiven. If that does not happen, the only figure you need to be looking at is the additional debt you would take on to finish you degree and whether a better paying job justifies that additional debt; given that you are in a dead-end situation, it probably does. Also, you will receive a boost to your morale from actually completing your college degree.

In the medium term you need to obtain correct diagnosis and treatment so that you actually can take on and successfully complete college education.
