How to stop relying on my best friend to meet new people?

Ok so I have a best friend named D and her 2 other best friends that go to another schools nams is C and S. D and S moms are bestfriends so they have known eachother since they were little. D and C went to school together when they were little. I have no problem with C, but the thing is that im jelous. she has 3 best friends and I have 1. and sometimes it feels like I have no one besides her to tell my problems to. Sometimes I cant go out without her cause im not that close to anyone but her, so it would b weird if I went out with my other friends and not her...u know? I feel like without her I can't make my own friends or be with other people. Me and C are becoming closer with eahcohter, but D is getting mad about it and doesnt want us to become closer. I keep telling D that if she wants me to not be friends with C I wont be. WOWOWOWOWO Anyways I want a way to become closer with D, and be closer to her more that C and S..so how do I do that. I want her best friend to be me and I want her to love me more than she loves C and S. I dont really like S so yeh.

I have a few other good friends that I would want to become closer with , and I have a feeling shes trying to get closer to them too.
So I want to have best friends besides her
I know its weird...but I cant always rely on her to make friends and be with all the time

I need to be with other people besides herr

please please help me

you need to find some other chicks that d doesnt no without telling her and then maake friends with them,then when you finally introduce d to them you guys will have some history and she wont be anle to make friends with them!!plus 1 best friend is beta than two,but it seems your friend is jelouse of u.I mite not no this but some people get jelous eof things they dont have she mite be jelouse that you becomming closer to someone other than her and she might be wanting the same thing,maybe c doesnt like her s much as u??
