Can my parents not let me live with them?

I'm going to explain. And I don't want pity.
I need help is all.

I'm a mature fifteen year old, who's looking to move out of her house.
I'm verbally and physically abused.
My parents are very two faced.

My sister left about a year ago into foster...

care. CFS left me here.
Now my friend knows what I'm going through. (S)he has informed her/his parents against my willing. But it's turned for the best. They've offered me a place to live till I'm 18.
I'm going to take this opportunity. But I have questions.
1. Can my parents not let me live with them?
2. Am I of age to make a choice in where I live?
3. Will there be court or any formal event to deiced my living?
If you do know of anymore information please let me know.

_note, I originally came to this site from google searching if anyone had any stories that I can relate to and I found nothing. I need this help.

if your're 18, you can do what you want. from the sounds of it, you have too get out. I went through it. you got any family that will let you live with them? it may not seem like it's right, but way better than living alone...trust me...

Your parents can say no and that's that

If Yu Let Docs Know They'll Find A Better Family For You.
