You can make friends. Saying you can’t shows that you need to change your mindset. You’ve clearly had some friends. College is a time to leave behind self-imposed ideas of “being popular (or not)” and instead focus on becoming a more mature version of yourself.

Every year, dozens of posts in this forum will be titled something like “no friends…homesick.” One such post had a great response from a kid who said he met his best friend outside the bathroom one day. You don’t have to have a lot of topics lined up to talk about. Just start out by saying hi to people and smiling. You’ll get there in your own way.
