Got a denial letter for unemployment, what now? - 2 weeks in

I was told my separation was for misconduct, which is not what happened. This is my first time dealing with any of this. My employer's version of events does not match mine, and I have emails that show it. Should I ask someone for free legal help?

Stay calm and stick to facts. Mine lasted about thirty minutes and felt more like a conversation than a trial.

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