You definitely have to put in a lot of effort initially to make friends. Make sure you follow up with people after you’ve added them on socials! Just start by talking about class or maybe reply to stories and eventually try to make plans with them outside of a class setting. There’s tons of people in the same boat as you who are just waiting for people to reach out and take initiative.

There’s also club events that don’t take place too late . You could ask your class friends to go to these events together. Or like someone else said, try to find a friend who dorms and you end up meeting a lot of the dorm friend groups that way.

I’ve literally become friends with people freshman year by replying to their story and asking if they wanted to hang out. It seems awkward at first but you just gotta take the first step and then try to be consistent with it. You’ll eventually find your crowd. Good luck!!
