My sister who's 74 and had alzheimer's for 6 years now , her husband says he can't care for her anymore , she only has incontinence problems , which he can't cope with , now she's been placed in full time care which I feel is way to soon , she's such a gentle kind person , cared for everyone , she was a midwife and worked endless hours , I go every day , it breaks my heart when she asks why am I in here what have I done , what do I say to help her , any advice would be brilliant .
