Dear annsixty, I do have some idea what you are going through (though only second hand as it is my dear brother). My SIL also had to deal with all the problems you mentioned and it wore her down completely. Most phone calls ended with tears and her spirits like yours were very low. My brother too is (was) fit as a fiddle and had no previous serious illnesses until Alzheimer's took hold. My brother became grumpy, moody, unmanageable and very difficult to deal with. In the end, with great reluctance, my SIL agreed my DB should go into a care home.
I believe (as far as I can tell) that he is content there. He is well looked after and is comfortable. My SIL visits several times a week and he always smiles when he sees her and hugs her. I think if you had asked my SIL 6 months ago how she felt she would have said she was at the end of her tether. Constantly in tears and exhausted with trying to cope. Life held nothing for her and she was very depressed. I went to see her last week and she was just like her old self. Laughing, chatting, going out, meeting friends and enjoying life as much as she can.
I feel greatly for all you are going through at the moment and maybe worse times are to come but I write this to encourage you to think that hopefully there can be more happiness for you in the future and some peace will come into your life again.
Please try and stay with us in the kitchen, even if you only pop in from time to time. I know most of the thread is lighthearted and when you feel very down it is difficult to cope with the frivolity of others.
The truth is ann however cheerful and silly we are on this thread, all of us have problems and worries in our lives. Sometimes it helps to share with others and get some support and other times we keep those things to ourselves. We do not really know each other in real life (with a few exceptions) but I believe the caring and thinking about others is genuine enough. I hope you don't mind but I will mention you in my prayers tonight and I wish you well.
Whatever you decide to do we will still be here. Please stay if you can but if not come back soon xx
