For Chanukah, it depends on whether or not I'm in a place where I can light candles. Last year, I was in the dorms, so that was out, and I basically did nothing. I switched schools this year, and I'm in a more unique dorm, so I have a kitchen that also has a switch to cancel the fire alarm, if it goes off. So, I think tomorrow some friends and I will light a menorah we'll acquire from Hillel, and make latkes to celebrate.
As for getting homesick, nope, and no presents either.
