Single dad of two who’s fallen on hard times

I’m a single dad of two who’s fallen on hard times. Last year I got into an unfortunate accident which required multiple Dr’s visits and the discussion of surgery. Since my kids require all of me, I had to put surgery on the back burner so that I could continue to work and provide for them financially. I was able to get medical leave in the event it became too hard to work. If I physically couldn’t go to work, I took leave and reported to my superiors as I was told to do. After months of following this same process, I was abruptly informed that I was being penalized because I didnt take additional steps to report absences, even though I wasn’t told to do so. I was suspended pending further investigation, but was told by managers that everything would work out and that I would be back to work shortly. I was told that this oversight has happened to others before and they were allowed to come back to work. After weeks of waiting for a decision, I was told that it could not be looked past this time without any further explanation. I informed my superiors that I reported my leave the only way I was told. I was given the run around and then ultimately let go. Even with knowing that I am a single father and that this matter was purely an oversight and not anything malicious, my employer upheld their decision to terminate me. I was told since the offense wasn’t anything “detrimental” to the company, I would be able to reapply after 12 months. I have been struggling to keep up with medical expenses since my kids lost their insurance. While searching for jobs, I applied for unemployment just so that I can have something for my kids needs. I received a letter stating that I’m disqualified from receiving any payments because my previous employer is stating that it was my fault why I lost my job. I now have to appeal which will take a long time. I don’t have the resources for lawyers or any aide. Any help that can be provided is greatly appreciated.
