Hi and welcome! You can check out my past posts for me being more long-winded...

But the short story is that my wife transitioned 5 years ago now, and I was about where you are when it was only a few months in - crying constantly, miserable, stressed out, and terrified - but we're still happily married now. So, yes, it can be done. (In fact, the largest study on trans people to date shows that about 50% of relationships survive, and I personally know quite a few where the couple is still romantically involved and bonded after transition. There's even a handful of straight women in that group; they redefined their orientation to have one *very specific* exception, because nobody gets to define your orientation but you. However, that is definitely a much harder road to travel.)
My primary advice early on is not to worry too much about the future if you can, and try to focus on coping with what's on your plate right now; if you can still say that you genuinely want to be with your spouse for the time being, that's answer enough *for now.*
What sticks out to me about your post, though, is that your spouse is not interested in helping you. I have to say, that's usually a bad sign - transition or not, lack of communication and failure to be considerate and take your wife's needs into account is a problem! Hopefully he'll get over it when he's past the initial stages himself, but you do have a right to your own feelings, and to make it clear to him that he needs to meet you more than halfway on this. The problem is that early transition can be a really selfish stage, when the trans person is so focused on how happy this makes them that they're ignoring everyone around them.
I'm afraid I don't have any good NY resources (though I agree that you looking for therapy and other help for yourself is wise!), but I can send you a PM with links to some online support groups on FB, G+, and Yahoo! if you want. You won't be able to reply to the PM unless you have 15 posts, but that's OK; I won't expect you to.
Good luck, and yes, even though it can get better - in the meantime, feel free to vent here!
awilliams, you mean well, but please, don't contribute to the doom and gloom.
