Got a denial letter for unemployment, what now? - 12 months and counting

I got a denial letter last week saying I left my job voluntarily, but I was let go as a copywriter. 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?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.

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