Best friend troubles :(?

ok, i used to hang out with this girl called Cindy, she was really popular, and we got along great, but we had a fall out because i wasn't aloud to go out and party all night at that age, but then i found this outher friend Georgia, aand we got along great and we had heaps in common, but she startded to hang out with cindy, and now she's different she goes out and hangs out with her way more than me, and say they are so alike, she makes out with randoms, and ditches me to flirt with guys, i remember when i first met her i was the skanky one, because she thought mini skirts were gross and slutty, now she cant get enough of them, but i dont want to loose her as a friend, because when we hang out just the two of us it's like the old days, but she changes around guys or cindy. Now i have no-one to hang out with, all my other friends are fun and stuff, but we dont really have similair interests, not like me and Georgia did. what do i do.
