Got a denial letter for unemployment, what now? (Oklahoma City)

I was told my separation was for misconduct, which is not what happened. There are 4 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.

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

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