Got a denial letter for unemployment, what now? - 2 weeks in

I got a denial letter last week saying I left my job voluntarily, but I was let go as a dental hygienist. I have not done a hearing before and I am nervous. If you have appealed before, what helped you prepare?

Thanks for writing this out. I went through something close to it 13 months ago, and it got easier once I kept a simple log of every call and form.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
