Continue what you’re doing, make sure that your curriculum fulfills the requirements of a wide variety of colleges, and challenge yourself. You seem to be doing that already, so I would say that you should carry on, and focus on enjoying your present life. You only get to be young once, you know.
You seem to be most interested in creative writing, which is good. There are a wide array of excellent programs in creative writing, in colleges with a aide range of acceptance rates, with the acceptance rate not being directly correlated to the quality of their creative writing program. So your dream college doesn’t have to be one to which your chances of being accepted are slim to nonexistent.
