Sorry that you've had such a shit go of it. I know firsthand how miserable and awful the healthcare system can be after dating a nurse for several years.
Not only is it genuinely full of some of the absolute dumbest people a person can imagine, over a period of time, they become so desensitized to the death and pain around them that they genuinely stop giving a shit. That was the hardest thing to see. People suffering and the nurses and Doctors being completely apathetic to it.
I hope you're doing well and are on your way to recovery. Don't lose hope. Feel free to vent any time you need it.
