5 Tips to overcome a bad mood quickly

Listen to music
Music is one of those strange almost magical things that has the ability to transport you back in time. It can also immediately change your mood.

Do something nice
Think of someone you can help. It's hard to be in a bad mood when you are helping someone.

Talk to somebody
If a friend or parent is not immediately available, teachers and counselors are often good listeners. Don't keep your feelings to yourself. They can fester inside you, making problems seem much worse than they actually are.
