Denied unemployment, how do I appeal? - 8 months and counting

My claim was denied after 21 weeks of waiting, and the letter says I have a short window to appeal. I would rather hear the honest version than the polite one. I have not done a hearing before and I am nervous. Should I ask someone for free legal help?

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