Am scared to live with my roommates anymore

So I have two roommates who are white and am black. I moved in with them late after they already become best friends and sharing everything. They offered me to share everything with but I decline because we're three girls in one room and their could always be a conflict. I have been keeping to myself for awhile letting do whatever they want. They can be messy to the point where am ashamed to have guests. So recently one of my roommates has been leaving dirty dishes with food around for weeks and I got sick of it , so I told her she should pick up. Instead of doing so, she talked to my other roommate who is her best friend and made a comment like " this is why we didn't need a third roommate " they both have a friend who is always over and she is always nice to me atleast thought she was. So I started talking to her since I was in the room with alone and it was awkward, and she got me to speak out about how feel about my roommates not knowing that she was texting them every word said. So what said I included that I needed roommates who are not white next year or if they white more calm roommates , I know I feel stupid for saying that. But they didn't talk to me they straight to report me and we had meeting that I did not know about with our floor leaders. And they were using that against me. I was not in trouble or anything we just signed our roommate agreement and that was it. But when I left the room and came back, they put a meme on our door of Donald Trump saying " are you mad bro" because I was upset when he won and they are Trump supporters. My friends at our floor saw it and took they meme off , then they put room 614 loves Trump . They doing everything to get me out. Please help I don't know what to do. Our university do not tolerate violence so I can't fight them cause I value my education. I need help!!!
