College student: is it normal i'm freaking out about growing up/life?

theres so much shit i've learned about life in the past few months, kinda. i thought it would help me grow but it just scared me. life is weird af! i'm college age. i started questioning and doubting everything i cared about and loved. it made me doubt myself. theres so much that we are unaware of about ourselves and surroundings sometimes. this sucks. i wanted to learn a few life hacks to avoid being a screw up. now i feel like it backfired because i tried to be something i'm not. i was already myself. but it just seems like people i know are all hipsters, vapers, and act so calm and wise. and they talk about life and politics alot. i'm more adventurous and fun. and i'm called immature for it.
