Denied unemployment, how do I appeal? - 12 months and counting

I got a denial letter last week saying I left my job voluntarily, but I was let go as a medical assistant. I have been trying to stay organised about it. The letter lists a deadline and a hearing process, but it is hard to follow.

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