You do need to take care of yourself to do a good job of caring for your wife. So much easier to say than to do, however. At least for me, we are both retired. I couldn't imagine caring for Spouse and working outside the home.
You continue to be in my thoughts and prayers, bobm, as does your wife.
So glad to hear she is improving albeit slowly. A whole lot of patience is needed in these circumstances. Patience is not one of my strong points. I trust you have your portion of patience as well as some of what I should have been blessed with.
