Can anyone give me advice about university?

In September I'll be embarking on a four year Philosophy course at the University of St Andrews, and I'm totally shitting myself. All of my peers seem morbidly enthusiastic about university, and are constantly raving about how they're looking forward to the great social life, and how many parties they'll go to, and how exhilarating the independence will be. When *I* think of university I feel nothing but dread. St Andrews is a good nine hours' drive from where I currently live in the West Midlands, so I'll be totally alienated from everything I know. I have extremely low self esteem, and consequently find social situations excruciating. The vast majority of people think I'm odd, and I'll be leaving my few very close friends down south. I have no particular longing to form more intimate bonds with people, but I would like to feel comfortable around my fellow students and know that they think I'm not too much of a freak which, as I see it, is a futile hope.
