Understanding the true identity of unhappiness

A moment of time may make us unhappy for ever.
John Gay   (1685 – 1732) English poet and playwright.
The secret of being miserable is to have leisure to bother about whether you are happy or not.
George Bernard Shaw   (1856 – 1950) Irish playwright.
Some things are of that nature as to make
One’s fancy chuckle, while his heart doth ache.
John Bunyan   (1628 – 1688) English preacher and writer.
Unhappiness is best defined as the difference between our talents and our expectations.
Lost, lost! one moment knelled the woe of years.
Robert Browning (1812 – 1889) British poet. 
It’s not what isn’t, it’s what you wish was that makes unhappiness. The hole, the vacuum…I think I think too much. That’s why I drink.
Janis Joplin (1943 – 1970) U.S. rock singer.
As it fell upon a day
In the merry month of May…
Everything did banish moan,
Save the nightingale alone
She, poor bird, as all forlorn,
Lean’d her breast up-till a thorn,
And there sung the dolefull’st ditty
That to hear it was great pity.
Richard Barnfield (1574 – 1627) English poet.
MEDVEDENKO Why do you wear black all the time?
MASHA I’m in mourning for my life, I’m unhappy.
Anton Chekhov (1860 – 1904) Russian playwright and short-story writer.
No one should ever ask themselves that: why am I unhappy? The question carries within it the virus that will destroy everything. If we ask that question, it means we want to find out what makes us happy. If what makes us happy is different from what we have now, then we must either change once and for all or stay as we are, feeling even more unhappy.
