I remember Steve! Unfortunately, I haven't been through exactly the same thing as you. By the time I started coming out as bi/pan to people, I'd already left the church and my family, and I didn't come to terms with my trans-ness for a couple more years after that, so I've never had to deal with that sort of religious rejection myself.
I will say two things that might (maybe?) help: first, there are some churches out there that are accepting of transgender people. Certain demoninations are better about that than others, and there are also some liberal and LGBT churches around, even in really conservative areas (I know a trans guy that used to go to one in Alabama, so you can probably find those anywhere). If you want to stick with Christianity, there's still a place out there somehwere for you.
The other thing is just that it gets better. Lots of people end up feeling disillusioned with Christianity for all kinds of reasons, and the first couple of years are where you resent it the most. For a while, it may be hard to let go of that resentment, but after being out of it for a while, that anger does start to fade, and you stop caring so much anymore. It's a little like going through a rough breakup. You feel angry and betrayed, like this person you loved and trusted so much has suddenly turned on you and doesn't love you anymore, and that's hard to deal with, but over time that wound heals, and you can start to let go of the past.
