Hey...
So I can't say anything along the lines of "I know what you are dealing with" or "I went through a similar situation" because everybody is different, and their experiences are just as endlessly varied. Your situation feels very much like you have people who dominate your life, give you no freedom and strictly repress you...that sounds pretty horrible to me.
What I can do, is try to offer you some advice from somebody who recently had a failed suicide attempt just last month. It's a long story, I won't go into here, but it involved a bridge, some friends who are far more intelligent that anticipated, the police, and an extended period of recovery in and out of a mental hospital...
So, having gone through it, came so close to the end, and somehow come out the other side, what can I say?
Well...I know intimately, that the worst feeling in the world is the feeling of powerlessness, that unshakable feeling like you have lost complete control of your life, that life is just some ->-bleeped-<-ty thing that is "happening to you", rather than something you steer or dictate. You think to yourself that there is nothing you can do to change your situation, nothing you can do to make your life better, and in fact that the only remaining options you have left, are to suffer endlessly, or bring a stop to it yourself. Sometimes it even feels..."right" like "I am making this one choice that nobody can stop, and that is something positive".
In times of extreme depression, your mind can execute feats of amazing mental athletics to justify suicide. I remember driving to the bridge and saying to myself "This will just be like Hiroshima...sure the remaining friends and family who love me will be devastated in the short term, but they will mourn and move on...and in the long term it will save numerous lives from decades of pain and suffering that would happen otherwise..."
Yeah your brain can be pretty dramatic and stupid in these times as well >.>
But don't do it. Don't throw your life away because of other people.
No matter how bad things are, they can always change, sometimes it's an over night change, sometimes it is a gradual change that takes time. But their is ALWAYS something you can do to make things better for yourself, you just need to find it.
If your parents are really pushing you to the edge of suicide and are not willing to help, maybe a drastic action is in order. I live in the UK, so it's possibly different in the states, so I can't give specific advice, but contact child services or something, put up a fight and show them that you are serious, it might just snap them out of it.
Even if it doesn't "fix" them or force them to come to terms with it, it is still something you have done, an action you can own. If it doesn't work, start thinking on something else that might help things.
Maybe it does not need to be something so drastic, like I say, I don't really know your situation intimately, but there is ALWAYS something you can do to improve your situation, you just need to think outside the box and look for solutions to your problems, rather than dwelling on how insurmountable they feel.
You need to find that survival instinct that all humans have inside of them, that urge to see another day, because you never know, it might just be better than this one, find it and don't let it go. There are kids in the third world who cling to underground sewage pipes at night for warmth, and eat from trash cans during the day.
If they can do that, then you can survive gender dysphoria and oppressive family. Better than that, you can survive, grow strong and build a happy life for yourself too.
I know it does not feel like it, and most days will be a struggle from the moment you wake, until you can get some professional help, but you can do it.
I firmly believe that every human being has the potential in themselves to fight through the most horrific things imaginable, to endure physical and mental pain that would cripple or send other creatures running. We can survive and learn from it, grow stronger and overcome our problems. Adapt and survive. You just need to find that drive.
You can do it.

Anyway I have ranted on for a while now...
