My mother (92) lives alone in an apartment in an assisted living facility. I live 6 hours away, but I try to visit every 6 weeks. I have a sister that resides in the same town as Mom. She and her second husband have taken over Mom's financial accounts. Mother is showing increased mental confusion. I visited her last week with another sister who lives out of town. Her apartment was filthy, and her refrigerator and pantry was full of moldy and old food. I had to stop her from eating old fudge with bugs on it. Mother is very proud and resistant to help. The sister in town is not dealing with Mom's physical needs. How do I deal with this situation without hurting my Mom?
