I'm so sorry, Anna. I lost both my parents to cancer. My mom when I was 17 and my Dad Sept 29th of last year. I know it's hard but if you can tell her, when she's ready, that it's ok to go it'll be that much easier on her. My Dad suffered and suffered and finally after 3 days in total delirium , he came back to us for one final day. That last evening, we told him it was ok to go, and he passed away that night. It seems to ease them a bit, if they know we're ok with it. I hope her passing is as painless as possible.

You're whole family will be in my thoughts.
