My Mom died from cancer, they told us she had about 7 days to live, but we had a short time to realize that she really was going to be gone. We did have the short battle, watching her not eat and wondering if the neon orange she had changed in skin color would be gone once she was gone.
Nothing like finding your mother looking yellow, then calling your sister to say, hmmm, Mom's coloring is off, she looks yellow to me I think something is wrong. We did have a few months of talking, crying, but her cancer had taken over and won this battle.
I say as long as your sister doesn't give up hope, and there are still drugs and treatments they can use on her that a miracle can happen. I will pray that the treatments available to her do work for her, and you will be talking and laughing with her in 5 to 10 years from now.
The doctors have given me a scare or two, but so far it only been a scare, and I haven't had to fight that battle in life.
Hey, if I had 1 in 10 chance to live when I became ill, and well, they said I might not be able to talk, walk, and all the other things I do today, there is hope for your sister.
I just wish she didn't have to go down this path in her life, but she sounds upbeat. It not going to be easy for her, her family, and friends. I wish all the best with this challenge in life.
