Seeing my roommate texting beside me, I always worry about whether I am talking to another roommate. . . How to adjust this kind of thinking?

The more you do this, the easier it is for others to think that you have a problem, and you may say nothing without saying anything. In this way, your high tension is not good for your health, and if you are nervous to a certain extent, you will lose control. I suggest you adjust your mentality, divert your attention, dilute others' views on you, go your own way and let others talk. This is a state and a kind of cultivation. You should practice, constantly improve your "immunity" and take part in more activities.
