My 91 year old Grandmother has recently started having delusions that her neighbors are after her and are starting fires in the middle of the night on her roof. She is under doctors' care, who haven't been able to diagnose her yet (this is all still very new). She calls 911 and the fire dept at least 2x a week... I've tried to tell them not to come, but they come and they are angry! This has been going on for 5 months. They keep telling us to put her in a home WELL, IT'S NOT THEIR G'MA AND THEY ARE NOT MEDICAL PROFESSIONALS SO THEIR OPINION is based on them being "put out". She has nighttime care so she's not scared. She still pays her bills, baths, laundry, cleans house, emails me, etc. and does not want a "baby sitter" during the day, which I understand AND respect. But.... I don't know how to keep her from calling 911... Any advise is appreciated!
