My flatmates are bullying me

Advice needed please, i have an issue where i yell in the night and i apologise to them PROFUSELY because of this. I can’t help it and they’ve tried to get me moved out of my room but apparently its too far in the semester, and if my problem keeps occurring then its useless.

That’s just a reason why they dislike me. But they keep laughing at me and calling me a freak when i enter the kitchen and they’ve started to use my fridge shelf for their stuff???? Im also in one of the same lectures as one of them and she keeps whispering to her friend and pointing at me whenever i see her. I know im not perfect and im kind of going through a lot right now but i never involve them with it. What can i do for them to leave me alone? It’s really getting too much. They’ve tried to get me kicked out of uni too and they’re causing me a lot of stress
