Happiness?

Lately, i'm feeling unhappy. happiness
noun
1.	state of well-being characterized by emotions ranging from contentment to intense joy
2.	emotions experienced when in a state of well-being

I feel none of the above.

I can't even recall when is the last true happy moment i had, 

and

I think i need a sleep now. 

Good night world of misery.
