I remember the feeling; I felt similarly when I first moved out of home to live on campus at Uni back in 2009. Until then I'd lived my life in a small rural town of 2000 people, but my Uni was in the country's second biggest city, a huge change of pace!
I'd second that you should focus on things you enjoy; play some good games, listen to music you like, read a book, go for a walk/jog, keep yourself occupied.
If chatting here will help, I'm happy to help out there. :)
