Get your head together, stay at home and be their for your parents you never know when you will no longer have them.
Make them proud do your school work there will be plenty of time to be grown up later! 
Moving out will not improve your feelings, in fact it may make them worse. You will not have the luxuries of home to depend on. There will always be a person madder then you out in this crazy world that might be a little tougher then you.
Get some help from someone who has the credentials to help you. It takes a stronger person to ask for help then to sit back and get into some deep sh!t because you were to scared to ask. Good luck and remember there are people that care! Times are tough give everyone a chance to cool down before making anymore rash decisions.

People are minors (and therefore under the control of their parents or guardians) until they attain the age of majority (which in most states is either set at 18 years old or requires the person be either both 18 and out of high school or at least 19 years old), at which point they become adults. However, in special circumstances, a minor can be freed from control by their guardian before turning 18. In most states, the circumstances in which a minor becomes emancipated are enlisting in the military and marriage, both of which require parent or guardian consent, or obtaining a court order from a judge.

The exact laws and protocols for obtaining emancipation vary from state to state. In most states, the minor must file a petition with the family court in the applicable jurisdiction, formally requesting emancipation and citing reasons why it is in their best interest to be emancipated. The minor must prove financial self-sufficiency. Many states require that the minor has been living separate from their parents or guardians for a period of time; however, consent of the parents or guardians is necessary in order to avoid being classified simply as "running away." In some states, free legal aid is available to minors seeking emancipation, through children's law centers. This can be a valuable resource for minors trying to create a convincing emancipation petition. Students are able to stay with a guardian if necessary.
