Assalamualaikum sister, wow what is going on with the parents today.. don't they love their children?? this is just really depressing....ok lets see if I can put in my $2 and be of some use inshallah
How old are you? because this is unfortunatly serious business.
Then looking at your age, the matter becomes somewhat flexible.
(Kinda sounds like my family on a daily basis also LOL, but I never really take them seriously.....)
First and foremost, sit down and talk to them.
If they dont listen.
Grab like a counselor and try again LOL
1) If they really want you to get out - then get out I guess.
(AND not like your gone outta the house for 4 hours and they call the cops

)
(Although make sure you have a place to go ... like perhaps a mature and understanding sister that you can live with)
2) Go to the mosque? and explain you situation, maybe they will try to talk some sense into them if the counselors didnt work?
3) Do you have any "mature" brothers and sisters?
4) Wait it out,till you got your own place.(thats what I am doing LOL)
Inshallah your situation gets better and May Allah make things easy and smooth for you.
Walaikumasalam.
