@rickjudy2012 Hello I just happened to read your posting. I’m Becky, a mentor for the Caregiving Support Groups. You said that living at home has gotten to be difficult and that you never anticipated growing old together would be do difficult or “like this.” Have you thought about assisted living? You would have a small apartment in a long term care/rehabilitation facility. The home makes all your meals, provides O2, and probably has physical therapy.
