Denied unemployment, how do I appeal? after 13 years as a sales associate

My claim was denied after 20 weeks of waiting, and the letter says I have a short window to appeal. There are 13 people counting on me, so I am trying to be careful. The letter lists a deadline and a hearing process, but it is hard to follow. 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.
