ummmm you have to find a place in 3 days or pay another months rent? Guess what, even if you were approved for this place you are in contact with, it may take more than 3 days to move in, set-up an appointment for paperwork, get electricity/utilities started.... so don't depend on being able to do that in 3... now 2 days.
The Military is a good option too, might want to look into that. I don't know how it is in your state but in NJ, they have lots to offer folks with disabilities. Like it has been mentioned already, there are jobs out there. They are not necessarily what you may want, but when it comes to making the dollar in order to live, you really can't be choosey. If you can find a job that is all you've ever hoped for, what a score. But especially given the situation you are describing, I would think you would take any job you could find. Jobs start from the bottom, and you work at moving yourself up. I speak from 23 years experience in the same job. I started at a low level and I climbed as I gained experience. Is my job my the hands down dream job in the world? No, but it gets my bills paid and I know without it, there would be things that I would have to do without. The bottom line is nothing has been handed to me. What have I learned? Nothing in life is for free, nothing will be handed to you without a price. You have to work for what you want.
