Being bullied by your roommate, talk about your mood.

Maybe you didn't blend in with them. First of all, people get along with each other, and no one will deliberately bully you. So you should communicate with them and ask them directly why they bully you. Maybe on the other hand, they are too arrogant, so don't be afraid of them. As long as you are right, don't be afraid of anything. Show them you have a temper!
