Appeal deadline questions after an unemployment denial (Jacksonville)

I got a denial letter last week saying I left my job voluntarily, but I was let go as an IT help-desk technician. There are 16 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?

Thanks for writing this out. I went through something close to it 12 months ago, and it settled down once I kept a simple log of every call and form.

Legal aid offices and some workforce centres help with unemployment hearings at no cost. A call is worth it.
