It's ok to be sad... It's ok to be unhappy... It's ok to want to scream and cry and all those bad emotions. Don't hold yourself to the standard of "the happy friend" or "the happy child"... No one is always in a good mood, and you shouldn't have to be either. Allow yourself to feel bad sometimes. It is way better then bottling it up and feeling all that pressure.

Allow yourself freedom to express more then one emotion
