I kinda have no friends?

Okay well this is the deal. ive had my group of friends since my freshman year of hs but as senior year comes to an end everything seems to be falling over. i try to fix things and were all good- until i realize they made a whole other clique without me for who knows how long. i was excluded from that group basically bc one of the girls(that was added to the group) didnt like me. i talked to her & fixed it. So we were all good. Then i find out they hang out all the time and dont even bother to tell me. its fkn bull. everytime i bring it up they brush it off. It really hurts bc they are supposed to be my closest friends but they jus basically dumped me for no reason. im going to college next year so idk if i shud try to fix things with my "friends" or if i shud jus forget it and move on. what do you think?
