Mr Moe,
Take a deep breath and know that you are not alone here. I am not from the NYC area but many on this sight have went to Sloan Kettering Memorial and received excellent treatment(use the search engine and you will see). You are about to start a very difficult journey but a very doable journey as you can see from the many survivors on this sight. As I have learned a cancer diagnoses always blows your mind and catches you off guard. I know exactlly how you feel as my father was diagnosed in January of this year and my entire family felt like we where in a hellish nightmare. Trust me when I say it will get better, time has an amazing way of helping one deal with things.
The best advice I can give you and your family is take it one day at a time, ask all of the questions that come to your mind, and don't get too far ahead of yourself(I guess repeating the one day at a time thing). You will find many on this forum that will be extremely helpful and supportive. Welcome.......
Kim S.
