Continued good thoughts for your sister and yourself, EG.
As I said earlier on this thread, I think I understand this kind of behavior somewhat: someone "strong", fiercely independent, very active, successful, prone to blocking out things that could go wrong (I think that is often required for a leader to be really successful), as long as it's possible. There have been quite a few people with similar tendencies in my life. It's not surprising to me that she has delayed emotional reactions at all. I hope she will find some peace eventually; it's fantastic that you can be there for her to the extent that you are. It's great that NYC certainly has some of the best doctors in fields that may be relevant to her condition.

When you do know, anxiety subsides or at least is transferred to something tangible, something that can be treated. You then have an opportunity to channel all that wasted fear, the wasted energy, by doing the things that are necessary to heal. Some people here might call this "acceptance."
I could not agree more with this.
Best wishes to both of you
