I am miserable and depressed!?

I hate my life. To be frank i cant stand anything anymore. All i ever cared about was taken away in a three day drive to one of the most hellish stats in America, yes you guessed it Texas. i lived in a small town in California for 14 years of my life, knowing nothing about the world out of the valley and the few places i had visited on vacation by plane. And my parents forced me to move to huge town and go to a school with a bunch of idiots. I am miserable, to be honest i just want it all to end, but i know that if i were to die in any way it wouldn't solve any of the problems that have been presented. (such as my hidden depression which i don't know why i am hiding cause i don't care about anything anymore) I am angry at my parents, (specifically my mom) i am sad because all i ever knew and ever wanted to know is gone, i am lonely because i hate everyone in Texas, and i hate my life in Texas, the rules, the laws it is all so insane. I know my only hope is to get out of Texas, i hope that i can convince my parents to let me move back home and live with my brother when i am 17 (but that is doubtful) and if that doesn't work i am gonna either run away or wait until i am 18 and just leave and never talk to my parents again. But the problem is i cant block everything out forever, i built barriers to help me ignore everything, to help me lock myself away in my room and wait it out, but it seems they are crumbling down a little day by day and i don't know how much longer i can hold them up. Sooner or later they are gonna fall over onto me crushing all that is left of my sanity. Just holding back to panic attacks to hard enough! how to i keep up and repair the walls i have built keeping the intruders out? Because this hellish nightmare seems to be turning into reality, to where i am no longer a third party observer and i am actually here in hell. Someone please help me. I beg you.
