If you can find something else you could do without school that might be one thing to consider. In my case, I wasted most of my time in college by doing precisely what you are afraid of… had I instead chased my passion, which would've been to make film, then who knows how things would, or could, have turned out. And you certainly need not go to school for that. 'The best way to learn (how to make films) is by doing.' My favorite director once said (who was also self-taught). But as it was or were, I can barely work a computer so if I had to go back & do it all over again I'd have certainly taken myself out, or offed myself, by the age of no-later than 24. (Because really… it was all downhill after there!)
