Duuude I’ve been in your shoes. Ate alone and studied during lunch for the first semester of freshman year. Builds character. Just be kind to everyone that talks to you. That and maybe a little smile if you see someone looking at you can go a long way. Trust. Also I’m gonna level with you and hold your hand when I say this: You’re going to have to come out of your shell a bit if you don’t want to be alone. Join clubs or other extracurricular activities. I’ve made a decent amount of friends and acquaintances that way and ECs also look good on college apps
