Natasha, please listen.
1.) Your state does not provide emancipation for minors, particularly not 15 year old minors, unless you have been married. NO state will allow a 15 year old to be married without parental consent.
2.) You cannot be emancipated in California, because you do not live in California. Nor will California emancipate a 15 year old except in very rare circumstances which do not apply here. The various states are not in the business of allowing someone to bypass their own state's laws.
3.) Just because you want to be emancipated, does not mean it will happen.
Emancipation is hard. It's supposed to be hard. Very, very few teens are granted legal emancipation under any circumstances. A source that I have reason to trust stated recently that out of approximately 10,000 applications for emancipation in the state of Georgia for the year 2005, 12 were granted; 9,988 were turned down. There is no reason to believe that other states are different.
Emancipation does not mean going to live with someone other than your parents. It means supporting yourself, TOTALLY. A couple hundred a month will not pay for rent, utilities, telephone, clothing, transportation, school supplies, medical care, shoes, shampoo, telephone, internet connection, etc. And without a sufficient income to pay for all of the above, not to mention a place to live that does NOT mean living with someone else, no judge will even consider emancipation.
Not being happy is not sufficient reason for a judge to emancipate you.
You need to get the idea of being emancipated out of your head, because the chance of it happening is somewhere between slim and non.
