Not without your parents permission, and even then it is n iffy thing. If your parents are neglectful you might be able to talk the courts into it, but I would think they would look for some older relative first.
Sorry, no! Not knowing all the details makes it hard to come up with a logical answer. Under 18 your parents are still responsible for your actions, well being and needs. You legally can't just pick who you are going to live with.
