New friend issue, my older friends are rejecting her! I can't stand it! I feel like crying!?

Wow, you have my life when I was your age (I am now 49yrs old). I went through the same things. Your friendships with the two girls are not friendships at all, it is called a "clique". I know it is hard but you have got to stand up for what is right. And stand up for your feelings and your new friend. She is the one who will be there for you through thick and thin. And it sounds like the other two are a little jealous of your new friend. The thing is, why would you care so much about what these other two girls think of your new friend? You need to be honest with yourself about that. True friendship is hard to find, believe me! So when someone comes along that you can relate to, snap them up. There is such a thing as soulmate friendships and this new girl seems like she has struck a chord in your soul that you can identify with. And that is rare to find. But you have to stand on YOUR principles, not the opinions of two insecure girls who won't like anyone you get to know because they have their "club" or "clique". Believe in yourself enough to do the right thing.
