Having a hard time adjusting to college

I'm having a really hard time adjusting to college, it's my second night. I have a bad anxiety disorder and although I think I did a pretty good job today I'm kind of having a hard time again. I miss my home (3 hrs away), my family, my friends, etc. I just feel like bawling and I have no idea why. I think I'm a bit overwhelmed too because I'm seeing all these people going out and having fun at parties and I haven't really went to one yet, I'm kinda shy. I'm trying to calm myself down but it's hard. Sleeping isn't really going well and I haven't been eating as well as I normally do at home so it's throwing me off. I don't like living in a dorm at all, I'm an only so I'm used to alone time but I'm living with 4 other girls. Any advice??
