No offense but knowing you I doubt you can really live independently. *shot* Anyhow, I think like Mango said, you should cherish the time you spend with your parents while you still can and try to understand even if everything they do/say clearly indicate they are TOTALLY nuts, because you never realize how much you love someone until you lose them. And I think in this kind of situation it's best if you can talk to your parents (though this is often IMPOSSIBLE to do, judging from my own parents) just so they can be informed of your opinion on your life.
Other than that I think you should stop bottling and pretending like everything's fine when nothing is. Now I'm not going to give you the usual crap about how we're always going to be here for you because 1) we probably aren't and 2) I personally hate hearing that myself. But find someone you know and trust IRL, someone you think will listen even if they are unable to understand your pain. After all, that's what friends are for (other than stealing food from ).
And finally I think this is mostly because we're teens. Stuck in between children and adults. We want to grow up, to be able to do whatever we want, to make our own choices in life, but we don't realize the responsibilities that come with it. We don't understand that adults really don't get to do what they want either. And we're not ready yet. Not ready to let go of our childhoods, not ready to be "big people." Fortunately (or unfortunately), the time will come for you to grow up and more likely than not you'll miss being a kid. If you just put up with your parents a little longer (however hard it is to do), they'll let you be who you want one day, and maybe you'll understand the things they do of which you believe unfair at the moment.
OML super long reply =x. *Hopes there aren't any grammar mistakes since I'm too lazy to proofread*
