What is the hardest part abut to moving to a new place

The hardest for me has been my social life because my social life here is different than the one I am use. In Mexico my friends and y used to go to parties every Friday and after that to sleep to a friend’s house, here we have classes on Saturday. Or each month I would go to the beach with my friends and go to clubs which you are not allowed to do that here. But the thing I most miss is my friends and my family. Also Mexican food. And all my customs.
