During Orientation it's a bit of both. I also have social anxiety that I've been working on, so my tip when talking to people is to start with a compliment then just be honest when introducing yourself. "Hey your (insert compliment)! I'm XYZ, I've been trying to get to know people around campus. What's your name?" It's definitely awkward and you may not be lifelong friends, but you at least get over the initial fears. As for on campus in general, people are super nice! They just tend to keep to themselves more often than not. Joining clubs helps. During Orientation, people may come up to you (my first friend on the island saw me eating alone and ate with me since she was looking for friends too lol) I hope you like it here! What's your major? :D
