Which friend group should I choose???!!!?

Ok...so I have a BIG problem I have a best friend that's been best buds with me since the 3rd grade (im in the 6th grade) and some more friends,but since I got in the 6th grade I was separated with everyone of my 5th grade buddies exept for one.I really didnt know what to do except follow the only friend that I had in my cl,then I really got to know her Best friends and they were pretty nice,I've met them before and all but never considered them my best friends,so I decided to follow my only best friend in my cl.Soon, volleyball came up and me and my only friend in my cl decided to join,and so did her bestfriends,then all of a sudden me and my friends BFFs became the best friends ever!!Then I spent so much time with them a sleepover and everything!!Then my friends from the other cl started complaing about how i never hung out with them and how i was getting more popular and was TOO popular for them (with my popularity guys started to become friends with me too and I was kind of hopeing for a boyfriend...)I said that I needed friends in my cl too and I would try to hang out with them more,but I had orchesta during my recess and choir on wensday after noons.Then me and my since 3rd grade buddy started getting farther.Since I was so popular (I usually have been but not this much)I kind of didn't want to hang out with them because now without me they were kind of considered nerds.....I need to know what to do I want to keep my new best friends and my old ones!!some one help!!
