Health coverage after losing my job: marketplace or Medicaid? (update)

My family's coverage ended with the layoff and we have a prescription we cannot skip. It has been weighing on me all week. I think my income this year might qualify for a subsidy. How fast did coverage start?

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.

Keep everything in writing and save the confirmation numbers. It saved me later.
