Your post echoes much of my discovery just a few months ago...
A gender therapist is a must. They understand your situation and will help you sort out the good, bad, and indifferent.
Transitioning from one gender to the other is like taking your whole life and throwing it into the air, where ever it all lands, it all lands. One must be willing to accept such a shakeup in their life to transition. It's that big, it's that challenging and indeed it's that rewarding.
One needs to realize the family they have before coming out may not be the same as after coming out. You mentioned SB...I'm in the same boat as you, they're not SB, but still rigid fundamentalists who shout Deut 22:5 but not follow through with rules, only 17 versese later, in Deut 22:22. They pick and choose to keep people out of their church club. Jesus said the fields are white (ripe) for the harvest. Jesus never said "only harvest what you think is useful to your community and leave the rest to rot". Sadly, that's what we see far too often with in the box churches.

It's a long road with more ups and downs than an east Tennessee back road, but it sure it worth it. Personally, I'm finding God has uncorked me to share His word much more than I ever have after my fork-in-the-road moment. I love it!
Hang in there girl, enjoy each day for what it brings you...ups and the downs. You'll learn more about yourself and those around you quicker now than you ever have.
