Well, unfortunately, you've done just about the only thing you can do.
There's no good news here except to stay healthy.
Things are definitely not going to get any better due to the massive aging of baby boomers who are going to need a lot of health care.
The only offset is the progress in new programs with the objective of keeping the aging population in their homes, which results in substantially less cost than caring for them in a nursing home. Most of the baby boomers want to avoid nursing homes like the plague, because they have dealt with that alternative with their own parents, many of whom have no nursing home coverage.
As a safety net, the best alternative as this point, is beyond the nursing home coverage that you have, you need an estate plan so that your assets aren't totally depleted before you qualify for Medicaid. There is currently a 5 year "look back" period where any asset transfers for less than fair value within the 5 year "look back" are added back to your assets when you apply for Medicaid and extend your waiting period for eligibility.
Perhaps that is something you should consider doing, ie. Medicaid Planning to back-up your nursing home policy.
