Hello. It is has been a while since I last participated in the forum but this post really caught my eye. I am 5 years or more in this journey and have experienced all of what you describe. My wile has no idea who I am and I regularly get sworn at - his morning I am a mean man and a bastard. Yesteday I was just a bastard. She constantly says she wants to go home (18 years in current home) and constantly wants to be with her mom - who died over 25 years ago. I am just a man who does all the jobs and she wonders how many other girls I work for. Her mood swings are horrific and can change in seconds. As pointed out these changes are common at bedtime. We have seperate rooms but I make sure she is in bed and settled before I go to my room. I could write a book on this journey but you get the picture. Two weeks ago she went completely off the wall and I had to call 911 as i could not handle it anymore (both 81 years and married 60 this year) and I just wore out, could not take it anymore. She went to hospital and their test confirmed she was healthy except for loss of memory and sent back home. We are coping but it gets more challenging as each day passes. I don't have any suggestions for you except hang in there and pray for help. Sorry.
