My own mother was very difficult to live with while we were growing up and far into our adulthoods. Finally, when we'd had it with her, we insisted that she get on medication. (Her Dr. suggested it to my sister.) It took all four of us standing up to her together to get her to do it, but she finally gave in. Today, she is a different woman; she's much happier and more positive and is fun to be around.

See if you can get your brothers to stand up to her with you and try to get her into therapy and perhaps on medication. After 76 years, it's time for her to be a happy woman and to enjoy the love and companionship of her family.
