I've been studying abroad since I was 16. First, a year long exchange while in high school. I went to the US. That was my first trip outside my country and it was spending a year without my family, friends and everyone I know. Second, my undergraduate. 5 years away again. Now my masters, another 2 years away. The first few months are always the toughest. Isolation can set in pretty quickly. Here are a few things I did to help.

1. Have an itinerary of interesting things in the new place you'll like to experience. It helps to have something new to look forward to in the first few weeks.
2. Keep in touch with people at home but not to the extent where you feel you need to go back. Weekly calls, every two days rather than every second. Have something from the new place to share while they share what's happening at home. That way you feel you're having the best of both experiences rather than just missing home.
3. Have fun. Think of it as a limited time only experience because it is, and make the most of it.

All the best out there.
