Health coverage after losing my job: marketplace or Medicaid? - what worked for you?

My employer coverage ended at the end of the month and I am trying to work out what to do as an operations analyst. Any experience at all would help. I think my income this year might qualify for a subsidy. 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.
