Denied unemployment, how do I appeal? - any advice?

I got a denial letter last week saying I left my job voluntarily, but I was let go as an accounts payable clerk. I am in Albuquerque, in case local advice matters. I have not done a hearing before and I am nervous. Should I ask someone for free legal help?

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.
