I went to an online high school. Without going to an online high school, I would not have graduated at all. Here are some intermediate steps and questions that suggest alternative options that may be more palatable to both you and your parents:

• Would your interests best be served by a school, or schooling, that is designed to get you through the minimum requirements with as little and as flexible work as possible, or a school, or schooling, that is designed specifically to challenge your intelligence to the very limit of its ability?
• Would your interests be better served by an online high school program? How difficult is it to get in once you apply? Is the school you want to go to accredited? (Read about national and regional accreditation for both high schools and colleges.) If the school requires you to pay tuition, can you and your parents afford it?
• What kind of paperwork would you need to complete to convince people who are supposed to keep you in school that you're still going to be learning? How difficult/tedious is the paperwork to complete? If you withdraw and "homeschool", will you still need to take the standardized state tests (US)? Will you have to make alternate arrangements for things like AP tests and the SAT tests because you are no longer going to your "neighborhood high school"?
• Are you old enough to get a GED and skip straight to community college classes? How about Bard College At Simon's Rock? Are you exceptional enough that a college's admissions board would overlook your (presumed not very good) academic record and admit you anyway?
• Can you take community college classes in place of some of your high school classes and get a dual high school diploma and Associate's degree, or get an Associate's degree in less than two years because of the credit you have already accrued in high school?
• Would your interests better be served by psychiatric treatment, including but not limited to depression or ADHD medication?

Good luck, whatever you end up doing.
