If your parents are against this, and the state has not made you a ward of the court and severed their parental rights, emancipation ain't gonna happen.
§ 16.1-333. Findings necessary to order that minor is emancipated.
The court may enter an order declaring the minor emancipated if, after a hearing, it is found that: (i) the minor has entered into a valid marriage, whether or not that marriage has been terminated by dissolution; or (ii) the minor is on active duty with any of the armed forces of the United States of America; or (iii) the minor willingly lives separate and apart from his parents or guardian, with the consent or acquiescence of the parents or guardian, and that the minor is or is capable of supporting himself and competently managing his own financial affairs.
You are not going to be legally married, will not be active with the armed forces, and will not be living apart from your parents with their acquiescence at that time.
If you are suffering from neglect or abuse, you can contact youth services or the police and they can investigate. That might mean a foster home IF the state feels that you are suffering legal neglect.
