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

My family's coverage ended with the layoff and we have a prescription we cannot skip. I have been trying to stay organised about it. I think my income this year might qualify for a subsidy. What did you choose and how was the process?

Thanks for writing this out. I went through something close to it 9 months ago, and it settled down once I kept a simple log of every call and form.
