Lost my job unexpectedly

Early July, a point system was introduced to ensure timeliness. You can earn up to 7pts before you get fired. I earned a few .5pts for being late. I also have peak insurance and was sick multiple times without being able to get an appointment to be seen. a week or two prior to getting fired I was sick, i didn’t feel my symptoms until waking for my shift (30 minutes before). I ended up calling out then and there to set a doctors appt. I had a lot of symptoms that made the urgent care believe I had COVID for testing, and gave me an absentee note. The note excused me until I received results, which was within 3 days. Not all of my points from being sick were excused. At this point i was supposedly at 6 points,. I believe the assistant manager gave me points without my knowledge and without me actually earning them. Though the point system is my cause for termination, they wouldn't disclose my file telling me how and when I got the points. When hired, my transportation broke down shortly after in Wyoming and was towed to a mechanic, and sat there for 4 months. We finally got the car back a couple weeks prior to me being fired. Something was wrong with the car, so we drove out of town to a trusted mechanic. So on the 21st Sept we got up at 06:30 and drove to fort collins (I was scheduled that day at 15:30). It had been leaking the oil into the coolant system, the electrical harness wasn't completely hooked up, along with hoses that were severed. It was a totaled hazard. We were instructed not to drive it for our own safety. I contacted my boss at 9 as soon as we knew. There was no way for us to get back to work. GM said it was fine since I called so early. Then AGM contacted me to reprimand me, threatening my job if I didn't show up, saying I would be fired. I contacted my GM to resolve the problem, and it never got addressed. I was deleted from the system and didn’t receive paystub info until 2 weeks after getting terminated. We also helped a friend out because their lease was up and asked them to cover utilities and they still haven’t sent the money because they personally feel like it’s not their responsibility to pay for the space they used for a month in our basement. But thomas’ paychecks are the only money we have til I get approved for unemployment. I worked really hard at my job and was being reviewed to move up, and the current assistant manager felt threatened and made sure I got fired. Now we’re behind on bills and I’m a student looking for work. Anything helps
