Sorry for your dilemma. Sounds as if you did all you could. Too bad for so many crazy dead ends. Be-at peace if you can. Pray for him to be comfortable. My hibby is in a nursing home with Primary Progressive Aphasia; Frontolobal dimentia; Alzheimer's. He has not been able to find his words and doesn't speak.. no longer frustrated by It, thank goodness. Yes and no answers. He smiles…seems to know us…not minding being unable to see us in inside. I miss him. Im very lonely. We visit through window at the facility or on video. Our kids all married with work..family are helpful tho. Hang in there. Sorry for your experience with the VA.
