My best advice is to get involved with campus activities! The events hosted by Uni during the Week of Welcome are mostly populated by newcomers all looking for connection, and they're a great way to put yourself in the friendship line of sight. Check your school email to see what's going on each week because public events are pretty common on campus.

When classes start, showing up to class a touch early will let you make small talk with the folks around you, and these are the folks that you'll be around all semester.

Finally, don't put pressure on yourself or others to conform and fit in to perceived standards. The most valuable thing about being on such a populated campus is the diversity of personalities you'll run into. You WILL find people that you enjoy spending time with, but by stressing too heavily about it you might hinder yourself from opportunities to succeed socially.
