Yes, my mother at 83 years old. CHF and surgery to drain the fluid till nothing worked any more and after the second episode of drawing off 7 liters of fluid, she said that's it and was dead 5 days later.
Her kidneys and liver had been so damaged over the years by the huge number of meds her so called "doctor" prescribed.....I tried for 30 years to get her away from him. We even put her in a mental health unit 4 times so he couldn't get to her. Just to get her off the meds. We all kept telling her that he was killing her and he came very close twice. She still thought he was a god and cared about her.
When the final days came and she was told why her body was shutting down, she said to us "Well, you girls were right. He has killed me" It was not a good death.....I still have nightmares about her final day.
I hope that karma exists and he gets his reward 100 times worse than what he did to my mother.
I'll keep you and your mom in my prayers.
