My Mother is 81 and her attitude stinks! Purely stinks! It is rubbing off on me and I'm getting depressed. I don't even want to be in the same room, so I go elsewhere. I am always kind to her but I'm truly sick of this living situation. I want her to move!!
Did her attitude always stink? Is this new, or more of same? How was she when you were growing up?
Why is she living with you? Is she a lonely widow, or does she have a medical condition she needs help with, or can't she afford to live on her own? Are you a caregiver as well as her landlord/housemate?
I'm not sure what your question is here, but giving a few more details and telling us just what kind of response you are looking for may result in better targeted answers.
