Losing employer insurance, where should I look?

My employer coverage ended at the end of the month and I am trying to work out what to do as a hotel front-desk agent. I am in Hartford, in case local advice matters. I do not want a gap in coverage. Is there help filling out the forms?

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

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.
