scared i wont make friends in college?

[Sarah]

It's always been really hard for me to make friends because i'm quiet and I can't just go up and talk to people. It's my senior year and I finally feel like i've been opening up more and having more fun, i'm just so scared when I leave my friends I won't make new ones. One of my best friends is going to the college also but he's a guy and we wouldn't be majoring in the same thing so I wouldn't see him that often, and he's shy too so i'm nervous that we'll just be so comfortable with each other we won't talk to anyone else. There's a facebook group for my college class of 2018 and 90% of the girls that post anything are like super gorgeous and I have absolutely nothing in common with any of them. Half of them are dance or physical education majors and i'm going to be a psychology major. And they all want to be in sororities. What do I do? any advice?
