Denied unemployment, how do I appeal? (Nashville)

I was told my separation was for misconduct, which is not what happened. I worked as a dental hygienist before this. I have not done a hearing before and I am nervous. Should I ask someone for free legal help?

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.
