Got a denial letter for unemployment, what now?

I was told my separation was for misconduct, which is not what happened. There are 9 people counting on me, so I am trying to be careful. My employer's version of events does not match mine, and I have emails that show it. If you have appealed before, what helped you prepare?

Thanks for writing this out. I went through something close to it 14 months ago, and it got easier once I kept a simple log of every call and form.

Legal aid offices and some workforce centres help with unemployment hearings at no cost. A call is worth it.
