Re: insurance plans:

1) will you qualify for medicaid or a subsidy? My friend who is a widowed single mom, bought a plan with low deductbles, but her subsidy cut the price in half.
2) Cobra your existing plan until you get a new one.
3) Do the math, but given your treatment you are probably better off paying for a gold plan with few deductibles than a bronze plan with hi deductibles. (I bought a bronze plan for 500/ mo, a gold plan was something like 825. I'm thinking about switching and getting everything I need done next year.)
4) if you qualify for Medicaid, take it! At least look at it.

Get someone you know who's good with numbers to help you compare plans.
