Losing employer insurance, where should I look? (update)

My employer coverage ended at the end of the month and I am trying to work out what to do as a school bus driver. I have read a lot of threads here and could not find my exact situation. The COBRA notice arrived with a very high price. Is there help filling out the forms?

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