Is it OK to feel lonely at college?

So I am a junior at my university, and while I've always managed to find friends, and have here, I still feel nagging loneliness. I want to branch out and do campus activities, but I feel really anxious about not connecting with my peers, or enjoying shallow relationships at best. I consider myself to be a somewhat confident, well-dressed guy, but I still feel like an outsider seeing everyone with their friend groups & significant others. I also feel extremely anxious about seeing some of my peers already getting married/ into serious relationships, and I've not really had any dating experience for myself. Is that ok, or am I lacking in some area?
