Denied unemployment, how do I appeal? - 7 months and counting

I got a denial letter last week saying I left my job voluntarily, but I was let go as a social media manager. I have read a lot of threads here and could not find my exact situation. 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 last year, and it settled down once I kept a simple log of every call and form.
