Appeal deadline questions after an unemployment denial (Knoxville)

I got a denial letter last week saying I left my job voluntarily, but I was let go as a warehouse supervisor. I have not done a hearing before and I am nervous. Should I ask someone for free legal help?

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.

Stay calm and stick to facts. Mine lasted about thirty minutes and felt more like a conversation than a trial.
