God bless you and your wife. If there is a medical school near you, I would suggest you call its Department of Psychiatry to see if they have a clinic. She may get assigned to a resident who is in training or she may get into one of the private practice physicians who teach there. In any case, I would bet just about anything that they take Medicare. Good luck to you and your wife. She’s a very lucky woman to have a husband like you.
“Find 100 ways”” is my motto! After all, in addition to loving her very much, she is a retired RN and I have to get her back into shape so she take care of me with my progressive neurological condition (orthostatic intolerance and ME/CFS) as I appear to be getting worse these days!
She is already back in the church choir, Christmas Cantata and secular holiday chorus...and therefore she is “warbling” around the house practicing, which makes my day!
