Haha, well... I'm sorry if I made you feel bad. And, uh, I have never been homesick during my studies, actually. I tend to quickly settle into new environments and make friends with people.
My friends and I would go out for dinner together, and on Saturday nights, we usually gathered to play card or board games. There were lots of activities to keep my days from getting boring, too, even during weekends; I used to conduct a choir for a morning Mass at the parish church, and then we would continue with a practice session. On weekdays, usually classes, gathering with classmates (which was almost always hilarious considering one of them is a truly funny guy), and studying really pushed all thoughts of home aside.
Yeah, that's a snippet of my campus life, haha... I remember though that I got homesick once when I was little, like, five; I went to my grandparents' for the weekend, and I cried that night because I had to spend the night away from my parents. Seen from the adult-me's perspective, that's embarrassingly hilarious, and such things always remind me of all the stupidity I used to do as a kid... XD
