Denied unemployment, how do I appeal? after 15 years as a production planner

My claim was denied after 8 weeks of waiting, and the letter says I have a short window to appeal. I have read a lot of threads here and could not find my exact situation. I have not done a hearing before and I am nervous. 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.
