1 entered a dead end and had to go in the other direction. When emotions enter an infinite loop, they should be temporarily put down. Emotion is not rootless, but something must affect you, so change the environment or go out to see the vast world and open your mind.
Simply put, it is to find a suitable way to vent your emotions and vent your depression. There is no better way. Otherwise, so many people wouldn't be sad. It is impossible to have an answer to solve this problem. If there is an answer, it can be solved. What mood is it?
Exercise is a tonic. Exercise can really relieve negative emotions. I strongly recommend running. If you don't want to go down, you can do sit-ups at home or something. If you really don't like this sport, dancing at home is ok. Exercise produces dopamine and makes people happy.
Cry if you want. Give vent to all your emotions, cry and do what you want. Holding back negative emotions will make you sad. Chatting with friends. Talk to some girls who you think are patient and gentle. A friend's advice is a good medicine
4 Let emotions flow naturally. Is it going to collapse? Then let it collapse. You'd better cry. Like a child, cry if you want. They usually just cry and have fun in the blink of an eye. We adults generally don't make ourselves sad, and the first sign will be a joke like you. But emotions often get stuck there. I suggest that every time I am in a bad mood, I quietly accompany my mood and watch it rise and fall. Don't worry, it will change.
