It feels like it wasn't long ago that I was your age, but it was a decade lol. As the others have said, friends do come and go. But i know its hard to let go of one especially if you feel she's the only one you have. If shes a true friend, you telling her that you don't like that, she should listen. If not, its honestly better to be alone than be around a person who doesnt respect you.
