Misty's Totaled Car and Med Bills

My car was totaled and it won't be covered. I'm a combat vet with previous back and neck issues that are now worsened.

I was driving down the highway slowly in poor conditions. Everyone was backed up bumper to number in the fast lane so I went to middle to be clear of dangerous conditions. Two cdot plow trucks were in the middle and left lanes. A transport van flew by me to pass in the clear right lane. I got over safely and much slower than speed limit and just started to get next to middle driver as they started slowing considerably. Little did I know they were slowing to turn. The far left truck cuts across three lanes and going through mine at almost a 90 degree angle, I had no time to stop and also began slipping on snow so couldn't slow. The officer said it was both our faults, though he didn't detail what I did wrong. I've been told multiple things, like I shouldn't have been in right lane, and those plows are considered inanimate objects and are extremely hard to win against. The two truck drivers seem to be getting their story together too. I'd like to file a complaint against the officer, they were both employees of the state and he talked to the cdot persons before during and after my report. Only speaking to me once and not asking questions or giving me any of their information. When he said he wouldn't cite them or me and metioned safe driving I defended my driving and to shut me up he said 'well I can cite you both.' Doesn't seem honest. He also didn't try to get the report from the middle driver (he left the scene) or find out about dash cams. 

I need a car now and the officer pretty much insured an unlikely good ending. No rental car, no medical, no car. I only had liability as the car was older.
I'd like to see a chiropractor and seek other care if I raise enough. 
I'm partially disabled but the VA doesn't cover chiropractor and only physical therapy. My back and neck have been pretty bad and flared up. It important to get care early. 
I just got this car this summer after the last car was totaled by a hit and run two years ago and I still owe 12k in medical bills. The damage is extensive and more than the car is worth. My car luck is terrible. 3 motors blown and two crashes. I'm a great driver with my full record almost clear of tickets and no crashes caused by myself or even fender benders. I also drove large diesel trucks in the military, fuelers, 5 tons etc and trust my driving so this is extra unfortunate feeling to me. 

5000$ is a base for me, I expect medical will be more but this is minimal what I'm hoping. Please share and personal message those you think can help.

Thank you so so so much!!!!
