I really really need help to make friends?

Hi, it sounds really sad, and please dont laugh, but I need to make friends. I do have friends, but they are the class above me. This really bad thing happened a couple of weeks ago, and my old friends In my class are holdin a massive grudge against me, it's not as if I haven't tried to make things better, I've apologised, blamed myself but apparently they all hate me -.- so I've tried to make friends with these two other girls in my class, but I dont think they really like me, and I'm worried because if they don't like me, I have no one. Please will someone help me become their friends and make them like me more?
