My husband's 94 year old mother lives with us and thinks the Feds are following her. She thinks "they" are withholding mailing her bank statement and threatens to hire a "big lawyer to fix it". We try not to engage her in this delusion, but she knows we don't believe her and this surfaces every so often. "There's nothing wrong with my mind! I know!" she screams at her son, "and they are watching you too!" My husband asks where are we supposed to go for help dealing with her? We can't have any outside help as she trusts no one, and of course my husband is an only child so we are stuck with her. It has been 5 years with no end in sight. Her doctors keep telling her she's strong and in great health, but they never see the delusions!
