Make an effort to be with people and develop relationships. Don't just stay in your room and think about how much you miss your family. Try to find a hobby/sport partner. It's not easy, but force yourself to get into routines like doing regular food shopping / cooking, going to the gym or exercising, doing chores like laundry, cleaning, etc. It's very easy just to stay in bed and feel bad, so try to push yourself to action. It will get easier if you become involved in the new country.

常回家看看。 QQ。 多认识些在你周围的华人。

I've been studying here alone for two years and still don't know how to reduce my homesickness... but i remeber it was tooo hard in the first day and i couldn't sleep too thinking of my family... I just miss them too much.

You can call you family and tell something interesting. Please don't listen to music which are really sad!
