Salaam - new roommate rearranged our place while I was away and now says I should move out for wearing hijab

Salam everyone, I really need some advice. A little background: I live in university-owned apartments and I’m grateful to have this place. I’ve had about five roommates so far, and alhamdulillah only one had a problem with me being hijabi before. I’m not proud of this but when I was younger I was curious about sororities. A lot of my non-Muslim friends joined them, but for some reason at my school the sorority girls are often unkind and sometimes try to push me away because I follow different values. This semester’s roommate is in a sorority. She moved in about a week before I returned from winter break while I was traveling. Usually new roommates message me so we can agree on basics or pick up a few things, even if it’s last minute. Since she didn’t say anything, I assumed no one was moving in or they’d come later. On the day of my flight she emails me with photos showing she’d rearranged the whole apartment. The place was pretty bare before because I’m a broke student, but I felt really disrespected - she’d shoved all my things into one corner of the living room and was proud of her decorations. They look nice, but she pushed my hijabs, my prayer mat, and the small mattress I use to sit on while praying (I’ve broken a bone in my lower back) into a cramped corner. I replied saying it looked nice and reminded her of two simple things I always ask of roommates: since I’m hijabi I’d appreciate (1) no men in the house and (2) no idols or photos left in a room I need to pray in. I didn’t say which room. We had never met - that was literally our first contact. She then emailed housing and CC’d me, saying it would be impossible to live with me. Housing sent me a follow-up saying, verbatim, “good luck on ur housing search” - to me, even though I lived here a whole semester before she moved in. She’s basically telling me I have to leave. Am I overreacting? I explained to housing that my previously sparse setup had a purpose for accessibility because of my health issues, and that past roommates and I always worked things out. What can I do now? I feel overwhelmed because her decorations are everywhere I move, like she’s rubbing it in my face while telling me to leave. We haven’t even spoken in person. I’m looking for advice or some validation - am I the unreasonable one here? JazakAllah khair for any help.
