What Is the Opposite of Meaning?

There is no such thing as a state known as happiness. Someone who is depressed can be sad all the time for a long period. But the equivalent doesn't really exist for happiness. The opposite of depression, for me, is not happiness, but it's a meaning, meaningfulness. If you spend a good deal o your day right and you're angry, frustrated, jealous or feeling ashamed about shit that actually isn't happening in that moment - that's the opposite of meaning.
