A) You have NOT been defeated! Period.

B) As you say, the battle begins now. First and foremost attack it as if victory is a foregone conclusion and the battle is an inconvenient, banal non-event.

C) Have faith in the Drs. you have chosen. Medical science is as much art as it is science. That is what a Nobel Laureate from the Howard Hughes Medical Institute once told me.

D) You will do great! You have lots of spirit, just focus it!

All my best.
