Friend looks down upon me?

Im in middle school and i moved to another district so when i first went there in 6th grade i didnt have many friends but now im in 8th grade and i have pretty decent amount. I have one friend i met in 7th grade. She was in my cl for two years. We became pretty close except now i feel like she looks down on me. Im short and shes really tall. She always points out things i wear some days. She sometimes gets pissed at me for no reason. One time i got mad at her but didnt say anything when she said i didnt have any friends in a joking matter. Whenever i talk about someone she says oh i used to be best friends with that person. Right now she might have said that 7 times and its annoying. One time we had to do a project with two other people. I had to do my math hw. She told me to not do it and we had to do our project so i put it away. Then she was on facebook. So i decided to start my hw again. Then she was like okay lets start. Then she goes like your not even helping. (All she had to do was import files into the comp) she told me i never do anything. So i told her she was just on facebook and even if i did help theres nothing i have to help with. That sort of shut her up.... Whenever i go to another friend she knows them too. We say ily to them (jokingly) and then she sort of grills me. Before she used to always call me short and at first I joked along with her but now its annoying. She got mad at me because i didnt tell her things that my other friend told her not to say. Lastly when we did the project, she left first. One of the other girls (she tends to cling to) she kept texting me about what we were doing and she said she was "curious" but im pretty sure its because she wants to be in on everything that happens. So i ignored her. When her and my other friend talks about guys she reminds me that i wouldnt know because ive never had a boyfriend. The truth is i dont want one. Thats that but shes like sure... okay. I dont want drama because im going to highschool soon anyways but her attitude towards me feels like she looks down on me. In the hallways she sees people i dont know. I dont care because she probably went to elementary school with them and i didnt. So... how do i change her way towards me? And she tends to curse at me sometimes.... not ever serious... maybe. Like Fck of ***** or something like that.... Sometimes when she says it she looks pissed at me or w.e. Please help? Should i wait it out or Solve the problem? and How?
