I am a 76 year old widower of about 2 and half years. My sister is 74 with uncontrolled diabetes which causes her to pass out and she has fallen and broke her shoulder. She has been acting unstable since before the fall, but she is acting bizarrely thinking people are listening on her phone and taking money from her bank account etc. etc. She is well educated but thinks everyone else has the problem. She lives alone and I live alone about 15 miles away. I am concerned because she is belligerent and domineering and has only 1 friend who is also concerned about her. We have no other family except a younger sister that is 62 who my subject sister hates and gets angry if her name is mentioned. I know she needs help but I also know she will not tolerate me suggesting that she get some help because she thinks everyone else has the problem. I don't know how to deal with this without completely alienating her. I know she will not be cooperative. I called a local senior services but they said without her consent there was nothing they can do. I'm at a loss because I can barely take care of myself. Any suggestions? Thank you.
