Denied unemployment, how do I appeal? (Pittsburgh)

I was told my separation was for misconduct, which is not what happened. I have been trying to stay organised about it. I have not done a hearing before and I am nervous. Should I ask someone for free legal help?

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.

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