How did you all resurrect with blood when you were very sad?
Find out your own strengths or things you like to do, and put yourself into them, work hard for it, strive for happiness, enhance your self-confidence, give yourself a boost in the future, and come on, so as to transfer your irritability. When your mood changes, calm down, think about your own shortcomings and correct them, so that you can rekindle your desire for life and devote yourself to the next work with pride.
