Got a denial letter for unemployment, what now? - 10 months and counting

My claim was denied after 2 weeks of waiting, and the letter says I have a short window to appeal. I worked as a warehouse supervisor before this. I have not done a hearing before and I am nervous. If you have appealed before, what helped you prepare?

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.

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