Arriving to a new campus with thousands of new faces surrounding you all at once can be intimidating for even the most popular of kids from high school.  You lost the comfort of being surrounded by all of your friends so no doubtedly that would make someone feel uncomfortable. The best thing you can do in this situation is be active and be yourself.

If you sign up for clubs that interest you or sports that you love, you will become surrounded by other people who have the same interests as you.  From this environment alone you are bound to meet new people and develop friendships along the way.
