Check and see if your state offers a HIRSP program. I was on it for awhile because I didn't make enough to get regular insurance, and too much for Medicaid. It has a high deductible but would cover a lot of your cost. Otherwise check the affordable healthcare act online. Good luck.
Honestly I'd call an insurance company independently. My grandparents faced a similar situation where they are retired, but too young for medicare. They were able to call bluecross blue shield & get awesome insurance for a really good price. Its no more that what they were paying through benefits w/ their jobs
Is there any way you can work a couple short weeks so that your paycheck is lower and turn that in for Medicaid
