Feeling lonely?

This is lowkey just me depressed at 2AM but I just started uni this year and I’ve made a solid group of course mates with whom I go to lectures with and sometimes go out with, but I feel I don’t really share any interests with these people. I’m also an international student and have been finding it hard to fit in and find other international students or just students from where I’m from. I’ve been doing my best to keep up with everything going on in my life but I just feel like I don’t have many friends who care about me. Don’t get me wrong, I have some solid high school and childhood friends but there are also some other people I considered to be my friends that after high school stopped talking to me or just stopped keeping in contact and I don’t really know why. I’ve just been feeling overwhelmed and I’m wondering how I can even make friends at this point. Just a rant
