Advice for Freshman in College

Vanessa
I need a lot of advice before I start school in August. I'll be attending Western Carolina University in the fall, which is 10 1/2 hours away from my family and boyfriend (we live in Florida). I know I'm going to have problems adjusting to being independent and making friends. I'll have a dorm mate and I'm kinda freaked about it. (I worry too much). 
What can I do to make myself confident in living "on my own" and what can I do about being successful in college?
