1st off- its college and an easy ass time to make friends. So just remember that. Now you can do one of 2 things to make friends (some good help here) you can start going to clubs/campus meeting and stuff to interact with other students. Or you can roll to parties with a bag of weed and smoke a bunch of heads up. I promise you will make some friends that way. :)
But remember 2 other things. Bitches run in crews they are like sheep so it might be hard to tag along with some lame ass crew of faggots cause you'd be the outsider. So don't worry about groups who are douches. And noone likes some clingy ass loser. If you're chill you'll meet cool people who want to roll with you.
But don't whine about it do one of the 2 things I reccommended and you'll have some kids to chill with soon.
As for your 2 boys fuck them. I would confront the one you think is the chiller, talk shit about the other one, and if he gives you cold shoulder or whatnot beat his fuckin ass.
