Appeal deadline questions after an unemployment denial (update)

My claim was denied after 25 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. 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?

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.
