Give someone a hug. Give your bf/gf a kiss. Write a cute letter to someone. Give a present to someone you love. Go a walk in the nature, and be glad for your life. Be happy for who you are. Don't try to be someone you're not. Dance. Sing. Paint. Play music. Listen to music. Look at old/fun pictures of your and your friends. Smile to people, and make their days better. Smile, just for your own, and be more happy. Call a friend and say that you love having the person as a friend. Just try to do something to get a good life, and love your life, 'cause we only have one life (someone meen something else), but be happy while you're living in that person you're now.
