So from now on, screw "perfect." Forget for a while about what kind of person you want to be, and just be the best version of the person you are. Figure out which of your classmates you genuinely like (not who you want to like you), and get to know them by telling your own stories and listening to theirs. Hang out with the people you think are cool, not the people you'd like to be considered cool by. Do things because they interest you, not because they make you look interesting... and then, take stock in a month and see whether you're not happier, healthier, and working on some actual friendships with other imperfect-but-lovely humans.
