Appeal deadline questions after an unemployment denial (update)

My claim was denied after 17 weeks of waiting, and the letter says I have a short window to appeal. I have not done a hearing before and I am nervous. Did you bring documents or only talk?

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

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.
