Denied unemployment, how do I appeal? after 18 years as an accountant

My claim was denied after 15 weeks of waiting, and the letter says I have a short window to appeal. There are 18 people counting on me, so I am trying to be careful. I have not done a hearing before and I am nervous. Did you bring documents or only talk?

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

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.
