I feel that when you are depressed, you should talk to someone you trust, a teacher, or a relative perhaps. Make sure its someone you can trust. You should not keep your feelings bottled up inside of you as they just build up and you just get more and more depressed. Going out with a friend or a group of friends could help you get your mind of whatever was making you depressed and the time with your friends would also make you feel a little happier. But always think positive and do not let your depression get to you just distract yourself and talk to someone.
