Got a denial letter for unemployment, what now? - what worked for you?

I got a denial letter last week saying I left my job voluntarily, but I was let go as a graphic designer. I have not done a hearing before and I am nervous.

File the appeal before the deadline, even if you are unsure. You can gather documents afterwards. That is the one part I would not wait on.

Keep everything in writing and save the confirmation numbers. It saved me later.
