"Sometimes I suddenly think of the scene when my parents beat me when I was a child, and then I start to get angry, hating my parents and myself for having such an unhappy childhood.
Sometimes I think about the people who were hurt by some wrong things I did in school when I grew up, and then I start to worry, afraid that others will say bad things about me everywhere.
Just like this, I often think about things that no one cares about and my mood becomes bad. Inadvertently, I have been hurting my family and friends with my irritable behavior.
I don't want to let anger consume my soul. "
