In Florida there is no such thing as emancipation of a minor without parental consent. It doesn't matter what your situation is; if your parents do not sign the petition for emancipation, you do not get emancipated. Period. No exceptions.
And even if it were possible, with no job and no income your petition would be denied anyway.
You have two options; you tell the DCF people the truth and see what they are willing/able to do, or you suck it up till you're 18. I'm sorry to be so blunt, but you simply do not have the option of leaving home without parental permission unless the state takes you out of the home and places you where they see fit. Those are your choices.
