I wouldn't ask him to NYC. Not only b/c you're leaving tomorrow, but b/c you sounded like you're really looking forward to spending it with you kids. Enjoy yourself. Try to breathe.
Like imp, my question would be what do you want. I know how hard it can be to answer that esp in the middle of all this. I have a trick(?) I use. I sit in front of the mirror and have a convo with myself as if one of me wasdying and looking back on my life. May sound morbid (btw that me is OLD), but I find I am actually surprised at the wisdom I possess. I journal so I record this stuff too. Sometimes something hits me rather quickly, somethimes it comes to me later. It's just another way to get in touch with what's inside of you.
