Please help a veteran pay off his debts

I am trying to get my life back under control after a severe setback. My bills are mounting and I'm finding myself more and more unable to take care of them. As of now, I've lost 4 jobs and have been denied employment at several other locations due to this setback. I am making approximately $1,700 per month after standard deductions, working 50+ hours per week. My rent and utilities total about $850, per month. My car payment & insurance run about $450. My personal loans payments come to about $300. That leaves little to nothing for food, medical and other expenses. I have about $20,000 of student loan that is now in default and am about to be garnished about 15% of my earnings. If I can make enough to pay off my loans, I should be able to get by with frugal living.
