Appeal deadline questions after an unemployment denial - 2 months and counting

My claim was denied after 14 weeks of waiting, and the letter says I have a short window to appeal. There are 3 people counting on me, so I am trying to be careful. My employer's version of events does not match mine, and I have emails that show it. Did you bring documents or only talk?

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

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