Bocchi's life is my life.
You don't necessarily have to make friends in college, but if it bothers you just try approaching people when a new course starts. You could use the pretext that you're looking for people to study together. Don't worry, every second person in the room should be as bored and unsure how to mingle as you might be and usually they are pretty relieved when they find there is someone to talk to about non-university stuff. And contrary to popular belief, the majority of those people don't bite and are decent and interesting folks.
