The weather is not very good today and I feel very depressed. How can I change it?

Bad weather will indeed affect your mood, mainly because the air pressure is low, which can make people irritable. Go out more often and chat with friends instead of staying at home. Don't let unhappy things affect your mood. Vent your bad emotions and try not to think about unhappy things. When you are troubled, you can find a place where no one is around to yell, find one or two close friends to talk to, and quiet down. Listen to music quietly, go traveling, go to the street to watch a movie or go shopping, go for a run, cry loudly, work hard, etc.
