NO support from my family.
NO support from my old friends. (had hardly any friends to begin with)
Essentially nothing from trans support groups. I checked out one, I did not feel it was for me, and I soon quit going.
What I did was, I went out and made TONS of new friends in the Pagan and LGBT communities (especially Pagans), and was soon having my best social life ever. I found there are a lot of very trans-positive people out there who gave me all the support I could wish for. Many people are just wishing for the chance to show support for trans people, if they could find any, and would warmly welcome you with open arms.
You should probably avoid Gardnerian, Asatrú, and Dianic, but in general, Pagans are probably the most promising bunch to find support among, and there are so many varieties, it increases your chances of finding some you like. I found a new spiritual home in
Witchcraft, where I got all the support and affirmation I needed.
What if you can't swing Paganism for religious reasons -- For Christians, I think the
MCC would be a good place to find support. Muslims are pretty much screwed, except that there is a Muslim LGBT support organization called
al-Fatiha Foundation. I know a Muslim trans lady in Cambridge, Massachusetts who is accepted by the other women at her mosque, maybe she got lucky. For Jews, there exist some
LGBT-friendly synagogues like Bet Mishpachah and Beth Simchat Torah.
For none-of-the-above folks, there's always Unitarians who are quite good on LGBT issues.
