What kind of psychology is it to want to eat in a bad mood?

This is a kind of psychology that seeks to vent. When people are in a bad mood, everyone does it differently. Some people like to go shopping crazily, some people like to travel everywhere, and some people like to stay at home and be alone. I think people who want to eat when they are in a bad mood are particularly cute. They are all harmless. Eating, as a way of venting, won't affect others and won't do anything that hurts yourself. It's good.
