I feel your pain. For most of our married life dh has worked for companies that do not offer insurance. I always choose the best insurance option from the company where I work - which is also always the most expensive. Most of time the companies I've worked for over the years are small and only have one option.
I was on home heath care for just over three months. At the time the best insurance option offered by my employer was a PPO plan. Home health care was covered at 80/20 after we paid a large deductible. My home health care bills including the meds, machine rentals and once a week nurse visits averaged out to about $300 or more per day

That means our 20% was over $60/day for over three months after we met the deductible.
Then I was remained on expensive meds for another five months. Just one of the meds cost $45/pill and I needed two/day in addition to four other meds. Despite demands from me and my dr, the insurance company would pay for only 15 pills/months so we had to pay out of pocket for 45 pills per months at $45/pill plus co-pays on the other meds.
We also owed $500 for each of the multiple ER bills, 20% for a radiology bills, a so many other co-pays it was crazy.
I am alive but we'll be paying off medical bills for many years to come.
Unfortunately my dh had a major injury the same year and ran up large bills all by himself.
Of course, we were paying the employee portion of the insurance at about $500/month plus my employer was paying even more. I can't imagine what the bills would have been without insurance but even with insurance it was outrageous.
I'm sorry I don't have a good answer for how to pay them off but just know you are not alone.
