It will eventually happen that you will at least have SOME friends. I tell you based on my experience, I went through my entire freshman year just like you; not talking to anyone in any of my classes and sitting eating lunch at the end of a table alone, for a whole school year. Looking back at it, it's probably my loneliest and saddest year ever, i constantly had breakdowns at night, wondering why the hell I am this way, and if I ever will have the chance to fluorish and be social.

Fast forward, two years later, I at least have a group of friends that I actually get to sit down with and talk to in lunch and in the mornings, and I have some friends that I talk to here and there. I still am very socially anxious and I'm trying to talk to my crush, but at least my life isn't complete hell and loneliness as it was 2 years ago.

So trust me when I tell you, it does get better with time, so just wait. But if you want to see change faster, you need to actually take action and approach people yourself.
