Feeling like I am not enough (canon much?)

You know, lately I've just been feeling like maybe I'm not enough. I'm studying in this very like expensive school that my parents can barely afford because I used to be good at studies in middle school. But here I am, among the elites, among the best of the bests, and I feel like nothing. You know, I used to have this angst in me that I'm not gonna be like the others and I'm gonna be different and extra. But now all I really wanna be is not different, not extra, just average. Everything's just moving so quickly, and I just want time to stop, you know. And I think I like quite a few people. I feel bad for liking many people. I don't even know at this point. I think that's average teenage, right? What can I be doing to actually make myself feel better? I don't know, guys. Tell me. What do I do to feel, to know that I'm not behind in life? Tell me about times you've felt this way too..
