My bedridden 95 year old father. I have tried to get him to see that the cousin of my deceased mother's help in my opinion, is not necessary because I am available to what she does, scheduling appts, helping out with my father's care and transportation needs. This cousin has taken on a very disrespectful attitude toward me. I believe she feels she can treat me that way because my sibling disrespects me in her presence. I need some suggestions about how to remove this cousin from her role and her overbearing presence in my father's house.
