I feel you
My best friend is still back at home and it's hard. I know we'll never separate fully, though.
I've made friends too, but it's nothing like my old friends, obviously. However, I'm lucky to have another one of my best friends here with me though she can be a bit of a bitch, I prefer not to be around her all the time. A lot of people I know were already here so I feel like I'm cheating in some ways.
