hi everyone! looking for some support (22F)

so I got laid off back at the beginning of June. it was my first job out of college and it hurt so bad. I was really depressed until I found a job at the end of July.

however, it turned out to be crazy, and they were making me work 14 hour days 7 days a week! (would normally be an office job that should be 9-5 M-F but remote work got them being too bold). I told my boss I was having a hard time adjusting, and told her I had a disability (didn't say bpd specifically) and that I needed a healthier work life balance and...she fired me. she refused to give me a written letter of dismissal, and now my last paycheck is $300 short.

I don't know what to do or where to turn. I got denied from unemployment because I was technically fired. I can't even report her for violating the ADA or something for firing me for a disability because it's my word against hers, and HR won't respond about my paycheck.

I'm just feeling really hopeless. I lost my cousin to covid back in April and things have just been getting worse and worse for me. I live alone, and without a job or unemployment, I'm not sure how I'm gonna make ends meet come November. I'm just feeling so low and lost, and now I can't afford therapy. it's like no matter how hard I try to build a good life for myself, I keep getting knocked down. none of my friends have gotten laid off, no one I know has lost anyone to covid, and I just got royally screwed by my ex employer. it's like life is just begging me to kill myself. I know I'm not strong enough to fight the urges anymore. sometimes I feel like it's not fair, but other times I feel like this is exactly what I deserve.
