Sorry for your loss. Having experienced it almost 10 years ago with my mother who died from stage 4 invasive breast cancer, I kind of know what you're going through. And that was less than a year after my dad passed from supposedly a heart attack...
After her fight with cancer for over 6 years now my mother passed in the afternoon..
the cancer had already spread to her meninges and there was nothing the doctors could do for her anymore.
I know i spoke a lot about it, to a lot of people here...
