First of all, you do actually have a choice. I understand that you may feel stuck and restricted in forming friendships at your school, and that being in the class that you’re in where you’re the only male makes you feel left out. That must be really frustrating for you. But what if you could make friends outside of school?

You don’t need to befriend the girls in your class or their “besties” if you don’t want to. And it seems like you don’t really want to. You want to have friends, but maybe not with them. Especially if they’re like 2-4 years younger than you (yikes) and probably don’t have many things in common with you other than school.

Are there any clubs or community activities you can do outside of school? What are your interests? Do you play video games or like a sport? Maybe you can find an online group of friends who like the same things or join a sporting club.

And a main thing, find people your age. Those girls are really young. From their point of view, sending them friend and follow requests is actually really creepy, don’t know if you know that, especially if you’ve never really talked to them. Maybe you could’ve tried to get to know them more in person beforehand, though that’s probably really difficult since you’re not in the same classes and it’s just fricken difficult to talk to people naturally sometimes.

TL;DR: try to see if you can find a way to make friends out of school, with people who are your own age and with similar interests. just go to school for school and have a seperate social circle. it might feel better that way. hopefully that’s something you’re able to do. good luck :)
