Why is the weather so good, but the mood is still very bad!

If you don't even know yourself, it means no. Don't give yourself negative psychological hints all the time. Emotion, mental state, sleep quality, etc. Are periodic. People will have high tides, and of course there will be low tides. This is normal. When you are depressed, don't pay too much attention and give yourself positive psychological hints.

This is just a low tide, and it will soon disappear.

Wait; You can also do some other activities you like, such as watching TV, watching movies and running to distract yourself. I will be happy soon!
