My mom-in-law, 84, was always an exceptionally wonderful person. Since my father-in-law, 8, had heart issues which are now resolved, she has started obsessing over little issues with family members and is completely alienated herself. She believes her brother-in-law lied about moving a brick or piece of tar between their yards. There is no rationalizing with her. This was always a close, fun, fantastic, loving family but now she can't even give her condolences to her brother-in-law for losing his beloved 37 year old daughter. She's said he, her sister and othrrs use the loss. My husband feels so hurt by her behavior and needs someone to give him some help. My in-laws live outside Pittsburgh unfortunately and won't come here and won't agree to getting family counselling.
