Feeling Insecure About Fitting In - Being Asian

I’m an international student, and I’ve been feeling really insecure about my appearance. Compared to many Americans or Europeans my age, I think I look more “childish” or younger, and it’s been making me worry about how others might perceive me.

I’m wondering do people in the U.S. actually care about things like this when it comes to making friends? Will it affect how I'm treated or included? My school has a majority white student population, and I’m starting to feel like maybe I should just stick to making friends with other Asians instead of trying too hard to connect with white students.

I’d love to hear any honest thoughts from anyone living in the US/who has been in the same situation.
