If this happens only in mathematics, it is probably a psychological problem. Sometimes when people don't want to do something or can't do something well, they will feel uncomfortable all over. People with strong psychological sensitivity may even feel sick, dizzy and sleepy. ...

If that's the case, I suggest you put down your school homework first and go to the bookstore to choose some math problems that are not too difficult, so as to exercise your mentality first and then your study. Don't be nervous when you do the problem. When you feel uncomfortable, you should choose other subjects to do or take a break before continuing.

If you are anxious because you want to learn math well, I suggest you review the knowledge points and formulas of this unit and the examples in class before making a unit, so that your thinking will be smoother and you won't get confused because you are stuck.
