Got a denial letter for unemployment, what now? - any advice?

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

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.
