Appeal deadline questions after an unemployment denial - 26 weeks in

My claim was denied after 26 weeks of waiting, and the letter says I have a short window to appeal. It has been weighing on me all week. My employer's version of events does not match mine, and I have emails that show it. 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.
