If you can be sure that you have mental problems, you can ask the school to come forward to solve them. If you are not sure, first see if you can mediate privately, contact other students in the dormitory to talk to him, and ask him to control his emotions, so as not to influence other students because of his violent behavior. If not, we can only ask him to leave the dormitory, or ask the student union of the school to help solve it. In short, people with different personalities should not live together.
