Appeal deadline questions after an unemployment denial (Nashville)

I got a denial letter last week saying I left my job voluntarily, but I was let go as a pharmacy technician. There are 6 people counting on me, so I am trying to be careful. The letter lists a deadline and a hearing process, but it is hard to follow. Did you bring documents or only talk?

Legal aid offices and some workforce centres help with unemployment hearings at no cost. A call is worth it.

Stay calm and stick to facts. Mine lasted about thirty minutes and felt more like a conversation than a trial.
