Appeal deadline questions after an unemployment denial - 7 months and counting

My claim was denied after 14 weeks of waiting, and the letter says I have a short window to appeal. I have read a lot of threads here and could not find my exact situation. I have not done a hearing before and I am nervous. Did you bring documents or only talk?

File the appeal before the deadline, even if you are unsure. You can gather documents afterwards. That is the one part I would not wait on.

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