Depression isn't funny. It shouldn't be played with. Not for attention. Not as a joke. Not as an insult to another. Depression is a real thing, a real problem. It causes unwanted thoughts and feelings that make the world so much heavier.
Happiness isn't a joke. It's real as well. Don't mess it up for people. It's a hard thing to achieve. Don't mess with other's happiness. Even if you don't like them. Everyone deserves to be happy at some point. It's important. It should be cared for. Not taken.
