Rejected while doing pre-employment paperwork

As the title says, I(30M) was rejected in the middle of doing pre-employment paperwork. All because I was let go from my job a year ago. It was never brought up during the interview process. I answered all questions honestly. I only had 2 more forms to submit and had letters of recommendation from my previous supervisors(the one included) on hand. I was about to finally get a career path going. I could finally move out of my parents’ house after 6 years of trying to get something going.

The rep only saw I was terminated but never even asked of context as to why. I worked for a hospital as a patient transporter and every single write up I got was a result from understaffing or equipment breakdown. A year later and those same beds are still in service, still doing what they did to me.

I’m beyond devastated. I’ve dealt with a lot in the past year. I was suicidal, dumped by my partner, quit a part time job because of the strain it gave my mental health. This is clearly a vent but I’m broken. I only ever wanted to help people. That’s literally all I ever wanted.
