Boredom

It's the state of being weary and restless through lack of interest. Boredom is rooted in the urge for meaningful activity or engagement that finds no satisfying avenues of expression.

Boredom can be divided into situational boredom (a temporary state of disengagement that nearly everyone encounters), and existential boredom (an unrelieved sense of emptiness, isolation, and disinterest, a condition intertwined with depression).
