Time to kick her to the curb.
My mother has been narcissistic, mean and nasty life long. I cared for her for out of duty for four hellish years. Now in a NH her journey down looney toon alley is outta sight - calling me screaming and getting me into a stroke/heart attack situation. I will visit, ensure she has all she needs and attend to her financis but I'm kicking her to the curb.
