The cooked duck flew away. Can you understand this feeling? How can I feel better?

I know very well that although you didn't eat the duck, you must have gained something in the process of cooking. When I am in a bad mood, I will read touching novels or movies and make myself cry. I will buy a lot of food to make myself full; I will also wander around by bus. Sometimes when I see that there are so many people on the road who are less happy than myself, I will feel that I have no reason to be depressed. My killer is to look at jokes and make up, and my mood will gradually get better with a smile.
