If you live at home you'll miss out on nearly everything uni offers. I didn't really like anybody in my flat in halls, which maybe kicked me into socialising more with people in other flats, you will make good friends if you stick to it. Forget about trying to maintain old friends, the true friendships you have will stick with you for life even if you only meet up at Christmas, the more general social crowd you know will soon disperse, people will move on and whilst it'll be fun to reminisce when you bump into such characters there's no point in clinging on.
As others have said uni gives you the perfect opportunity to move out of home and become independent, with everyone in the same boat it makes things much easier. If you just come in for lectures your unlikely to be able to see anybody for long enough to make true friends. Stick to it and join some societies, you're bound to find one full of like minded people who link you into a much wider network of friends. Whatever you do don't just sit in your room worrying about everything, you will soon get more confident and the more you try the more confident you'll get. Take all the opportunities that come your way without thinking too hard about them, you'll never get them again.
It's also worth noting that if you really want to move rooms or halls your university will go out of their way to try and help you.
