You gotta do more. People around you must have attempted to talk to you, you have to interact with them. My first few days in college, I responded to everyone and absolutely didn't care what they would think. You might think that my stutter was mild but no it was and still is severe, it does limit my social life a lot. Find peers with similar interests, I was interested in tech and Sports, so whenever there was a discussion about these topics going around, I participated and in the end made a handful of friends. Just those first few days of talking might be awkward, after that it's smooth sailing. College students are expected to be mature enough, they won't think any less of you. There are a lot of kind people out there.
