Question Marks💔

I am currently a first year college student. I am really confused and blank-headed why am starting to lose my enthusiasm. I graduated as a natch valedictorian, but when I entered a university everything just suddenly shifted. I am not that pressured when I come late to my classes, be absent, and even just attend and comply for the sake of requirements accomplishment—no more goal-oriented version of me. Grrrr I feel drained and down, yet I do not also know why I can still handle to laugh and make other people smile🙂‍↕️😮‍💨
