Poor you, poor your whole crew! "Month from hell" is no exaggeration. Sorry you've been going through this, and I hope for less eventful days ahead.
I can't improve on the advice everyone else has already offered. Before our diagnosis, I was a worrier, and always wanted to know -- what's next, what's likely to happen, how can I improve the outcome. A terrible prognosis (the initial info shared was worse than the reality has turned out) cured that pretty quickly. I hope that's true for you too, so that to some extent you can avoid borrowing trouble. Try not to worry. Doctors have to be vigilant and cautious. I'm hoping and expecting you'll get good news after they do all the due diligence.
