Got a denial letter for unemployment, what now? (update)

My claim was denied after 26 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?

Thanks for writing this out. I went through something close to it 2 months ago, and it got easier once I kept a simple log of every call and form.

Legal aid offices and some workforce centres help with unemployment hearings at no cost. A call is worth it.
