Got a denial letter for unemployment, what now? - first time posting

I was told my separation was for misconduct, which is not what happened. I am in Nashville, in case local advice matters. I have not done a hearing before and I am nervous. If you have appealed before, what helped you prepare?

Legal aid offices and some workforce centres help with unemployment hearings at no cost. A call is worth it.

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