I am soooo sorry to hear this. I know it's tragic, and want to thank you all the more for the warning. Maybe I can share something that may be of small comfort to you.
My mom was a good person to many. Her friends looked a lot like refugees from the very hardest of life's difficulties. Most of them were infirm or had something that severely impeded their lives. As amazing and big hearted as she was she wasn't without her vices - she was a heavy smoker, former drinker (though by the time she passed she hadn't drank in 25 years) and she was a big caffeine addict. My mom was diagnosed at 56 with terminal lung cancer. She went through treatment and we had three great years with her before she passed at 59 (a month shy of her 60th birthday) A few months before she died we were told the radiation they had given her as preventative a few years earlier, hadn't worked and she had 6 tumors in her brain - of various sizes - the biggest being the size of an egg. It looked like it was going to be a long horrible and painful death facing her. (I lived through my friend passing last year at the age of 48 - from peritoneal cancer - its a special kind of horror to say the least) Less than a month after getting this news, my mom had a bowel perforation - her intestine was blocked and it had burst. She became septic and passed peacefully within the week. As painful as it was to lose her, I was also grateful she passed so quickly and relatively painlessly. She was a good person and didn't deserve to die a slow and painful death. I am not a super religious person, but I do believe in god and have found comfort in the belief that he took her home to him before she really had to suffer. Hugs
