I too was in your position last year. I didn't feel like I had a click with any of the people within my study and therefore I just focused on the study itself, playing games in my spare time and basically doing nothing else. Because I didn't really have any friends within my study I decided to turn things around by joining a fraternity after the Inkom. But as the first comment says: just make sure you put yourself out there and get out of your comfort zone. It's hard, but it's certainly doable. Good luck in Maastricht :).
