Hi Allyson,
The Witnesses that you are meeting and who are making you feel welcome are doing so because of Conditional Love. They love you on the condition that you do everything that the Organisation says, and act and think the same way as everyone else in the congregation.
And even if you try and conform to their ways once it is known that you are Trans, the love will stop.
When I was a JW there were two gay men in my congregation. One was a pioneer who tried to deny he was gay. He ended up having a nervous breakdown, leaving the JW's and going "ultra gay". But the few times I saw him in the street he looked tormented.
The other chap was a study who tried to change himself to conform, then tried to be accepted as gay but still study but who was eventually driven out of the congregation by the passive aggression showed towards him.
I know gay and trans are very different, but they're not to the JW's. They're "Wrong" in their eyes and will never be accepted or accommodated.
