What do you do when you are sad? Do you cry or find other ways to vent? I think you can read books, and when you see people who are more miserable than they are, and they are strong and brave, your mood may be better. You can also listen to music, so that you will forget about the sad thing, and be absorbed in the beautiful music. It doesn't matter what makes you happy. What matters is that you need to have a positive attitude to face life and overcome the pain!
