Please Help. Veteran & Family Evicted

I am a medically retired Army Infantry soldier with an 80% disability. I am married with four children, ages 16, 13, 12 and 7. My disability pay is barely enough to survive. Over the past five year's- I have tried working, but nothing has worked out because of my medical issues and my really bad physical days. No one wants to employ someone who has to take a lot of time off because I cant walk or stand up on my own most days. I suffer from severe headaches caused by a cervical spine injury. The headaches are often so severe that any movement is excruciating. I am also take 17 medications daily prescribed by my VA doctor that prevent me from being fully functional. We have had things come up over the past year that have made stretching my disability pay even harder. It has culminated in us being a month behind on rent. We owe just December's rent, but our landlord is evicting us on December 26th if we can not come up with the $1000 for December's rent, the $100 late fee and the $500 in eviction costs before the day after Christmas. We git the paperwork from the sheriff's department today. Also, we have shut off notices for our power, which includes our heat, and our water. I have gone to every agency I can find and have been told that I do not qualify for assistance. I honestly dont know what to do. My wife and children are in danger of being homeless in less than a week, the day after Christmas. We arent even able to give the kids an enjoyable Christmas before this happens because of finances. I am just hoping there is some people out there who arent in this situation that can help us out in this time of severe difficulty for us. Please help if you can. Thank you and god bless.
