I would strongly dissuade you from ending your formal education at this time. That said, your career accomplishments qualify you as 'child prodigy' in the eyes of college admissions counsellors, on the one hand, and successfully graduating with C's / D's will if anything hurt your case. Get your GED. Find a good, large community college at 16, and begin there on a part-time schedule, perhaps 12 credits a year instead of the normal 24-36. Get straight A's or don't bother. Now, at any time in your progress towards a "2-year degree" (including after graduation), you can transfer out to a big-name university and have most of your classes count. You have an academic track record that shows you can successfully study, and an extracurricular that outweighs anyone else's. It enables you to focus your learning, remove yourself from the often harsh social environment of high school, and put off the decision about whether you'll begin a traditional college experience for years, and still be ahead of the game age-wise and credibility-wise. There is a reasonable chance that your business will fail entirely, or be sold profitably in the next five years, and this route provides you with long-lived options, without wasting the time you're wasting now.
