I don't know how much longer I can do this.

We've had a tumultuous marriage. I was in the army, but recently I was medically retired due to some nerological and mental health problems. About a year ago (when I started having pretty serious medical issues that lead to me losing peripheral vision in my left eye), my wife decided she wanted to move to MS when I got out. We went and looked at house and bought one on the beach (it was a dream of hers). She moved down there while I stayed in GA and finished up my medical retirement. We rented out the house that we lived in GA.

I found out she was cheating shortly after that. We went to the courthouse for a divorce and the judge awarded her primary custody, $1100 in child support, I have to pay half the mortgage on the house in MS ($1800 of $3600). In total almost 3k of my 5.7k retirement. Due to my medical issues I haven't been able to find a job and the rest of my bills (to include paying for and repairing a broke down truck). Due to the above I can't afford to rent anything so I'm functionally homeless. I don't qualify for assistance because I make too much.

What the hell do I do?
