My sister is the primary caregiver and in charge of her finances (which are plentiful) and she totally enables my mother to constantly complain about illnesses, inability to eat, everything negative. Mother is very inappropriate in social interaction and mostly refuses to go out unless it is totally for her appointments, etc. She takes no prescription meds but lots of health supplements. It has caused a great deal of friction in our family although this is nothing new! Mother has always been this way, but now it is growing worse by the day! And my sister refuses to be reasonable about ignoring some of this bad behavior. I was a former educator with an emphasis in psychology so I know about setting boundaries, not enabling, etc. I am at a loss as to how to apply what I "know" as this has become so personally frustrating. Thank you for any helpful suggestions.
