First of all, 15 is young to be emancipated. In most states you must be at least 16 and there are many states that do not allow emancipation at all. And one of the most consistent requirements in those that have emancipation is that you show your ability to support yourself. Your relationship with the place you are living will be a matter of contract between you and them. If they set rules for you to follow, and you don't want to follow them, find someplace else to live. They are certainly within their rights to kick you out, you are no longer a 'minor' that requires sheltering by anyone else.
