It has been three days since then, and Leon's depression got worse as time passed. He locked himself in his room and refused to come out. He curled up on his bed and covered his body with the blanket.
He had no mood for anything. He kept remembering all the sad and bad things that had ever happened to him.
That was a normal mechanism of the human brain. It would show us every sad and bad memory of your life when you are feeling low, and it would make you more miserable.
