Previous employer got me denied unemployment

Tried to file for unemployment cause I got fired, just to find out that my previous employer got me denied because of misconduct due to absences. Which would be fine, if it wasn't for the fact that I was led to believe that I could have it fixed.

I spent weeks trying to turn in doctor's notes to get my absences excused, and my boss told me that HR could do it. Then HR told me that it was my boss's duty to do that. So guess what never got done?

I finally filed an ADA case when I realized that they just weren't going to do it, and then while it was ongoing they fired me.

I'm not gonna do anything about it, I don't have the means, but it just sucks. I tried to do everything right but now it just seems like it's my fault. Like I asked to develop chronic pain. They should've just fired me when I reached the threshold instead of leading me to believe I could keep the job. They fired me two weeks after the delinquency, after reassuring me that they were gonna help me the entire time. Seeing that denial letter just pissed me off, none of this would've happened if they'd just stuck to the rules in the first fucking place instead of giving me hope.
