Friend [F/21] tells me [M/22] that we can no longer be friends because of personality differences

A few days about my friend [21/F] started become more distant towards me[22/M] as she stopped saying "hi" when we would pass by or just interact with me less. As a result I grew concerned that I might have pissed her off and I began texting mutual friends if she has mentioned anything about me getting her mad. As I sent those texts out, my friend tells me that we can no longer be friends anymore because of personality differences. The backstory is that we've met probably around last fall and got closer last spring semester. Our relationship is strictly platonic and I never had any intention of dating her. She mentioned that since we have met, she has had problems with me but forgot about them because she had to deal with a personal issue and because we didn't see each other too often. We have probably known each other since last fall and we hung out a few times in the spring and summer. Prior to the end of last spring semester, she asked me to have the same schedule for this semester and live in close vicinity of each other which I agreed to both. Over the course of the summer we hung out a few times to grab food. She claims that she acts toxic to me because she is constantly annoyed at me and even with the episodes of her being toxic, I looked past it. Receiving the texts made me feel heavy hearted knowing that I had just lost a friend that mattered to me and furious as it made me feel like I meant nothing to her since the start. This text was sent to me 2 days ago and I have had to see her everyday because we have the same classes. I just didn't understand why she would say this after we plan for similar schedules and living conditions. I was initially furious but I have calmed down as I have vented to some friends and become more at peace with the situation however, the fact that I have to see her face everyday for the rest of this semester kind of enrages me a bit. It has been two days since she has sent me that text and I have left it on read. I don't even know how to respond, I'm speechless. Should I even try to speak to her or should I just move on and ignore her. I have never been faced with this situation and I'm genuinely unsure of what to do.tl;dr: Friend texts me saying we can no longer be friends anymore because of differences in personality. Initially had issues with me and forgot about them but tells me now after we schedule things close each other.
