I live,
But live to die: and, living, see no thing
To make death hateful, save an innate clinging,
A loathsome and yet all invincible
Instinct of life, which I abhor, as I
Despise myself, yet cannot overcome —
And so I live. Would I had never lived!

George Gordon, Lord Byron (1788-1824) English poet

Cain, Act 1, sc. 1 [Cain] (1821)
