My Mother, Louise ( as she liked to be called!), died from complications of Pneumonia and Congestive Heart  Failure, at the same time. She suffered from Diabetes, one of the worst cases I ever seen. Prior to her death she was nearly blind, losing about 80% of her sight, had a toe on her right foot amputated, and eventually lost her entire left foot to amputation, just below the knee. She was placed in nursing homes on 4 occasions, discharged from all of them, due to medicare regulations and policies, and had  home health care twice in a year. After medicare stepped in and disallowed her to continue home care, we ended up taking care of her. Me and my brother were already taking care of her for nearly 2 years prior to her death. When you run out of options, you have to do it, she's my mother, and she raised me and took care of me. Through those years, taking care of my mother took it's toll on my health, but she's my mother, I felt obligated to do it!
