When you are in a bad mood, it is difficult to let go of your worries, that is, your mind is in a mess and it is difficult to attend classes wholeheartedly. What should I do?

The other is caused by poor eye sleep, sometimes half an hour away, which may affect the spirit of the day. Never ignore the role of going to bed early and getting up early, and remember to develop good clock habits.
