This girl is stealing all my friends?

[claire<3]

There's this girl and she's nice and everything but she's really outgoing and kinda bossy and sometime's she'll leave people out and make them feel really awkward. Because she and a couple other of our friends take all the attention, they are also starting to take all of my friends. They're always hanging around with my friends and leaving me out. But what I'm really worried about is my 2 best guys friends. I love them to death and I call them my brothers and they call me their sister. We can tell each other anything and we always hug each other and are happy to see and talk with each other. They're a lot of fun to joke around with and share ice cream and hang out with. They're really cool, but my friend-stealers think so as well and I'm worried that they will steal my best guy friends. I know I should trust my friends, but these people are really good at stealing friends. What should I do? The friend-stealers will just laugh at me if I try to talk it out with them.
