Sorry to hear that it's not a good situation at home.
I agree with the others - your gender issues can't be hidden away to make your parents happy. This means that you'll have to take some concrete, practical steps towards becoming independent. The whole living with the parents thing doesn't sound like it's going to work.
It's hard to get started in life these days, but it's a hurdle you'll have to overcome. Believe me, I've lived life looking backwards and feeling sorry for myself, and it's not a good place to be. Breaking out of that cycle is so important, because the future does hold lots of promise for you.
So, if transition is your goal, then leave the past behind, leave the comfort of your parents behind, and focus on two things: employment and accommodation. Employment first - that should be your number one goal. Once you have that in hand (and financial independence), you'll find that what your parents think really doesn't matter that much anymore. Without any more info about where you live and what you skills are, it's difficult to offer much more advice, but generally you should look as broadly as you can - if you want to transition badly enough (or if you just want to live your own life and see what happens), you'll find a job doing something somewhere. It might take doing something you consider beneath you, maybe something miles and miles away from home, but what matters is that you get that regular paycheck. Things start to fall into place after that.
It's a long, hard road, but it's in no way impassable. And it sounds like you'll be walking it without your parents at your side, so it's extra hard.
Maybe you can get your parents to help without them knowing they're helping? Perhaps don't mention anything about you being trans to them whatsoever. Instead, tell them that you'd really like their help in sorting out your employment issues. Tell them you have social anxiety, that you might benefit from some therapy to talk about it, and how you'd also like them to do what they can to motivate and assist you in a job search. Show them you've turned a corner, that you'd like to try your hardest to break the cycle of unemployment. They may even offer to help provide a little extra financial support if your job doesn't pay enough for you to live alone.
It's got to be rough, and many of us know what you're going through. We're here to provide as much support as we possibly can, even if just a friendly and safe place to vent.
