Medical and auto help for disabled Vet

Thanks for taking a look at my page. I'm a disabled American veteran who has recently lost his kidneys. It has been a huge strain on my life. The failure of both my kidneys is connected to diabetes(type1) from a viral infection I sustained while I was on Active Duty. I am receiving care at the now infamous Phoenix VA. I didn’t really get much attention from a doctor until I was in the Emergency Room with 50 pounds of water on my legs and having a heart attack. That’s what it took to get in the door after 2 years.
I am currently on disability through the government but I am not getting the checks that were promised to me by the VA for my disability. I’m on an extremely tight budget and I’m having trouble affording some recent additional expenses. As part of my overall health, my dentist needs to do two root canals and two crowns. The estimated cost for this procedure is $3,000. In addition, my mode of transportation has broken down. It’s extremely important that I have a vehicle to get back and forth to my dialysis appointments. The estimated cost for vehicle repairs is $1,000. Any help would be greatly appreciated.
Thank you again for taking the time to read this and an extra thank you to those who can help financially.
