Read up on shock..Symptoms happen months after the actual event. Even read about PTSD also very appropriate for a cancer dx. I think we all go through levels of both.
Cancer sucks. Ain't no way around that. But she also could have been hit by a bus.
We need to take our blessings one scan at a time and stay in the present moment. Can we learn how to be more at peace from our cancer dx? Is this the lesson we are meant to learn?
