Hey Brittany. I just started my second semester at college (I, too graduated hs in the spring), and I had a lot of the same worries you did. Luckily for me, I was able to go to school a week early for marching band, and was able to make friends, so the beginning of classes wasn't so scary for me. While you obviously can't go in a week early to find your way around like I was able to, you CAN go out of your way to be friendly to others, so you can get the opportunity to make new friends and have people to explore the campus with
