She has delusions and doesnt know she is even home and it is hard for me not to argue with her or tell her she has lived with me for 22 years. she says no i have to go home and cook and get ready to go to school. what should i say especialily when she wants to leave. I try and get her mind off of going home by changing scenary or going for a ride in the car but everytime we go out and come back home she doesnt remember her home and says she wants to go home. She thinks I am her sister most of the time.
