I'm not sure that all the pressure, frustration and anxiety are worth it. This can cause health issues for both of you. Maybe just discuss finding a more affordable location to live and make it on the joint social security you have. I know that sounds cheesy, but it's sort of what I had to do when I realized I had to survive on one social security check. Sometimes, living a peaceful life is worth giving up other things for. Just enjoy the time you have with what you've got.
