Roommate and venting 😅

I’m in college and my roommate is like CRAZY. She acts normal somedays and then all the sudden she will start yelling up and down the hallway and screaming over minor things . And then she will be rude to me over small things . For instance she didn’t get a bid for a sorority and she made a big deal at it and yelled and screamed at people LOUDLY up and down the hallway. I’m stuck with her because I’ve moved rooms to much due from other terrible experiences how do I handle this ?
