Think yourself as a tourist to overcome homesickness
Think yourself as a tourist and try to explore your new country. Visit new places and gather new information. Make yourself as an adventurist, go for trekking in hilly places. Go to the most popular sites and attractions to get to know the city like a vacation right in the beginning. Wandering through the country, you could get to know the countrys culture and history right away. When you have a good feel of the place, begin to find "your people", your niches, the places you feel most comfortable. You can also look for a restaurant that has food you are obsessed with. Find parks and relax yourself. You can start as a tourist, then be an expat. This can help you in getting over homesickness.
