What I would do to start is do all the research you can on the subject. Knowledge is power. In the meanwhile, go to your local employment agency and ask for help on finding work whether it be resume help, interview skills, or what have you. Once you get work, stress will decrease. If you can't get what you want for employment, take something temporary and keep looking for what you really want. At the same time gaining valuable job skills. The longer you are out of work, the more difficult it is to find work. If you can, you could also consider going back to school for a degree. Not giving up on anything whether it be transitioning or looking for work is key.
To get your folks on your side, I recommend offering assistance wherever possible (doing odd jobs and such around the house) and be as kind as you can to everyone. It may take time but eventually you will be in a better position to discuss your gender issues with them. Plus, once you have a job you can afford to go to a gender therapist and talk about what's going on. That person could also give advice about how to deal with your folks.
