Hi I'm sorry for your problems Your in my prayers. It was the opposite with my mother she was undergoing radiation for lung cancer. She had the cancer licked. She started having problems and we took her to the hospital. After we checked her in and they put her to bed we finally left her at 12:30 am my sister and I traveled home During this timne she had a massive heart attack. it came from out of no where as she never had heart problems at all. They lost my mother that night when I tried to call early the next mornign they could not find her. After several franic calls i found out she was in intensive care. We rushed to the hospital to find her on a ventilator. I stayed there with her every day and only left late at night . During that time I never got to talk to the doctors. They use to leave by the back door of intnesive care. We knew nothing. Finally after a week one of her nurses took me aside and said her vital organs were dying. I went ballistic and made a scene.and finally got to talk to the doctor. he said her heart had exploded. there was nothing left of it to beat with out machines, but her brain was fully functioning. So everytime she had a code blue they would resusatate. After days of this her cancer doctor came out and said we can keep doing this until all her organs fail or we can pull the plug. We had to choose. My brother ,sister and i taked it over and he told them to do it. She died a few minutes later. It is hard but I can say we were at peace. my mother never wanted to be on a machine and was very angry when she woke up on one. You will know when its time. Be at peace and remember what she means to you.
