When we are in a bad mood, we can try to adjust our mood in the following three ways.
Method one; When you are in a bad mood, you can divert your attention by consciously changing the subject or doing something else, such as listening to music, watching TV, playing ball, playing chess and taking a walk. This will ease the mood.
Method 2; Tell your relatives or close friends about your troubles and even cry, or throw pillows, sandbags, etc. To vent the accumulated troubles in your heart, which will also be beneficial to your physical and mental health. But you should pay attention to the object, place and occasion of venting to avoid hurting others.
