Need advice regarding uni conflict
To keep it simple, I've had an intense situation at uni and need advice on what I should (or shouldn't) do.
For context, I'm at an art uni and the class is really small, so we're all forced to interact with eachother one way or another.
For the past year, one person, let's call them Max, has been getting progressively more irritating, doing things like sitting directly next to the professors (which the professors never addressed, although it's strange), randomly bringing them things like flowers and mushrooms, and commenting and laughing at other students' works, ideas and presentations, including mine. They also lately started commenting and advising works of their peers like a professor, suggesting what to leave out or do differently, which really set me off.
Anyway, recently the whole thing escalated when Max came to class in the middle of my presentation (the professor briefly went outside) and started ripping some papers and then making a speech that sounded like it was pre-written. They said that they needed help from us and that they felt uncomfortable coming to class everyday because of us, disregarding the constant feeling of discomfort I felt everyday because of them.
It's important to say that at this point their behaviour had started to really affect me on a psychological level and that I'd already planned on calmly confronting them in private soon.
Max asked what it was that made us behave that way towards them and I snapped while standing directly next to them (because I was presenting) and said that it's because of their behaviour. They said that they were sorry and that that won't happen again and asked to hug me. I was confused and said ok, and they hugged me. The professor came in and asked what was happening. I was shaking.
I continued presenting and they sat directly in front of me and started making loud and frequent comments about my presentation.
Me and my partner went for a break to the store and I was visibly upset. When we got back, Max was waving some papers around (that were allegedly a diagnosis of a panic attack) and saying how they wish that such a thing never happens to us. They spoke in a very theatric voice and most of us thought it was a performance. However, they started talking about how we should all come together everyday (although we're not so close with eachother) and speak about our problems. I said how I come to class because I have to, not to have group therapy, and they started shouting at me. I got upset and ran outside.
I hadn't seen them since and they're allegedly getting help at home, since the professor had called a psychiatrist because of how they acted.
My problem is, however, that I keep having bad dreams and anxiety about them coming back. I really don't want to go through the same thing all over again, especially since now, if I say something to them, I might come off as insensitive because of their personal problems. My partner suggests ignoring them, but it's a really big deal for me. I don't know what to do.
If you made it so far, thank you. I'm curious of what others would do in my situation :/
