You should think about what's wrong with you, or some personality reasons lead to this situation. After all, people in the university still know something. Those pure bad guys are still quite few. You can't deny a person because of some trivial things, so as to expand your influence and lead to your depression. If your roommate deliberately targets you and makes you angry just because you don't fit in with them, it's rubbish. The only thing you can do is to relax, do what you should do, get rid of this kind of person, and don't go along with this kind of person in the future. Don't get angry when it's unnecessary, and don't think about ideas that hinder you. Find your own life.
