Losing employer insurance, where should I look? - first time posting

My family's coverage ended with the layoff and we have a prescription we cannot skip. 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?

Losing job-based coverage usually opens a special enrolment window, so check the deadline on the official marketplace site. I missed it by a day once and regretted it.
