You can even feel homesick when you moved in your home country away from everything you know.
But the impact can be huge if you are abroad.
What worked for me was staying connected with my home country: keeping up with the news, watching some tv channels, introduce some traditions you feel good about it, cook your favourite meals if possible and stay in touch online. Now days it's easier than back days. But also embrace your new surroundings, explore as much as you can and keep your mind open.
Even now there are some days that I wish I was back and I let it come to me, knowing the next day it's gone.
I never forget the first moment when I was in the big supermarket in a big mall when I saw some products which I knew from my home country. And to read my language on the package.
