Appeal deadline questions after an unemployment denial after 16 years as a medical assistant

I was told my separation was for misconduct, which is not what happened. I have been trying to stay organised about it. 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.
