Denied unemployment, how do I appeal? (update)

I was told my separation was for misconduct, which is not what happened. Any experience at all would help. I have not done a hearing before and I am nervous. If you have appealed before, what helped you prepare?

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

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