I know how you feel, rural environments can be horrid, and the solutions may not be apparent but I think there is always a way forward. That way forward might not be terribly quick though.
Are there jobs like Best Buy, Target, or the like near? or is your small town even smaller? If there are jobs like that around you may be able to get something so that you can get some money to move out. Those two in particular have store polices protecting gender identity and sexual orientation, though they might not be always enforced, even if you aren't out, it isn't good that someone could out you and get you fired.
once you have a bit of cash you can do anything, move, get certs, go to college, etc. I have came to the conclusion that financial independence is really the only solution if you want to transition without really wealthy and/or supportive parents.
What I would do, is try and build a goal in life, such as transisiton if that is what you want, then define the specifics of what that goal needs, such as the total amount of money, where you need to move to, etc. And then define what you think you need to accomplish those things, such as education, or transportation, etc and then break those down into small easily attainable goals.
I know I feel really good when I accomplish a goal, even a tiny one, that puts me further to what I want. Just make small little steps and try and try not to rush too much, and try and enjoy the ride. I for one, know I wanted too long, and feel the burning urge to make up lost time, but I know that haste can be detrimental to good planning sometimes.
