Ha ha! Psychological pressure is great! At the same time, I can see that your courage is not big enough, including your social circle and circle of friends are not wide enough, which shows that you are introverted and you lack exercise. Have the opportunity to run more, play basketball, relax your thoughts, transfer your mood more, ask the teacher more questions at ordinary times, and summon up the courage to answer questions in class. . . This will solve all your problems.
