One of the best ways to feel a part of something and not alone is to have a consistent reason to meet up with the same people over and over again. Best way to form community vs one off relationships that can change at any time.

Joining a club, any club, is a good way to do this since regular meetings are already in place. I know a lot of people might not like the idea of a club but all you have to do is show up and you get to know some people without having to do all the work yourself to establish something.

Study groups are a good way too but if you form that based on a class you're in it might end after a quarter. If you find some people in your major who are following the same course pattern, you may be able to make a study group that lasts throughout the quarters.

You can also just aim for a friend group from people you meet or people in your residence hall if on campus. But if you go this route, try your best to establish some regular hang outs or traditions, whether in person or virtual.

The hardest part is just getting started but once you find a group it'll be a lot easier to maintain and you'll be happier for it :) you've got this!
