Denied unemployment, how do I appeal?, bank teller here

My claim was denied after 10 weeks of waiting, and the letter says I have a short window to appeal. It has been weighing on me all week. The letter lists a deadline and a hearing process, but it is hard to follow. If you have appealed before, what helped you prepare?

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

I printed my emails in order and wrote a one-page timeline. The hearing officer kept going back to it.
