She's also quite verbally abusive. She is way worse with my dad, who is still very viable, but to an extent does this to us all. She never was an easy person to like or get along with but its getting so much worse. She is in a significant amount of pain due to a back problem. But she acts like a petulant child that was never taught any manners in addition to getting outrageously angry if she thinks she has told us things that we know she hasn't. If anyone tries to help her, i.e. attempt to reason with her or encourage medical intervention, she thinks we are ganging up on her, telling lies about her and generally wanting others to think she is 'crazy'. She complains all the time and is never happy; although when gently confronted she is shocked- says she NEVER complains and is the happiest person around and how dare us try to make her look like she isn't?! Its driving us crazy. Are there any books or material to help? I am oldest daughter and primary caregiver, outside her home. Any help is so much appreciated.
