Denied unemployment, how do I appeal? after 16 years as a payroll clerk

I was told my separation was for misconduct, which is not what happened. There are 16 people counting on me, so I am trying to be careful. My employer's version of events does not match mine, and I have emails that show it.

Stay calm and stick to facts. Mine lasted about thirty minutes and felt more like a conversation than a trial.

I printed my emails in order and wrote a one-page timeline. The hearing officer kept going back to it.
