What to say....I am so sorry this has happened to you. Have you called your Dr. here in NC and told him his screw-up?
I don't have any advise for surgery, It is unfamiliar territory for me, but I am here to support you, and since we live fairly close if you need anything when you get home, I hope you will contact me.
I do know a bit about NYC however, and I know that there are social workers at Sloan that can coordinate transportation and lodging for you. There are even flights that are donated by "Corporate Angels" that can fly you and your husband back and forth for free. I know from a cousin who's child was treated there for cancer, that there is a Ronald McDonald house close by. Maybe the social worker knows of a place for adults? Since they are primarily for families of children. I am sure there are discounted rates for families who are only in NYC for Medical reasons and this may be something to look into.
Again, I am here for you, and I am so sorry you are facing this surgery. I am glad however that you were smart and went to NY for a second opinion. Who knows what would have happened if you continued with you Dr here.
