It’s been 1.5 months since school started and I don’t know what to do

My college life just started as a freshman, and in our college we have a system where we have the same classmates in the same classes for the duration of our stay. Even though it’s been weeks since school started I haven’t been able to make friends in our group and it even seems like they don’t want to talk to me. They’ve already made their own friend groups and I’m the only one who feels like an outsider.

I tried to approach each and every one of them to see if they wanted to talk or make friends and each time they don’t feel like doing so. In fact there was never a time where I was approached by someone else, it always seems like I’m the one going to them. Every time I go to school I get more and more demoralized, and I hide it with a smile when I’m in front of them so as not to look negative or give off bad vibes, but I’m getting more tired.

Honestly I’ve been having a hard time since grade school, and nobody wanted to be my friend even before, for reasons I don’t know. Nothing’s changed since then, and all the “friends” I made disappeared once the school year was over. I don’t know why but I’ve tried everything I can do – speaking to them, going on outings, playing games, and still nothing. Should I just give up and accept that nobody’s going to like me?
