How do I decide between two great things?

The only cles left at my high school that would benefit me are Astronomy, Zoology, and Trig. I'm also on the student council, volleyball team, a tutor, STARS program, NHS (as an officer), you get the idea. I want to take cles full time at the local community college but I would have to give up my senior year, most of my friends, and my extracurricular activities (the college is an hour away from my school). I would have to rent an apartment there and move out at the age of 17. Educationally, it's the best option for me, but socially it's not. Should I stay at my high school and not have any intellectual stimulation, or leave? Advice?
