Sonnet CXLVII

MY love is as a fever, longing still
For that which longer nurseth the disease;
Feeding on that which doth preserve the ill,
The uncertain sickly appetite to please.
My reason, the physician to my love,	5
Angry that his prescriptions are not kept,
Hath left me, and I desperate now approve
Desire is death, which physic did except.
Past cure I am, now Reason is past care,
And frantic-mad with evermore unrest;	10
My thoughts and my discourse as madmen’s are,
At random from the truth vainly express’d;
For I have sworn thee fair, and thought thee bright,
Who art as black as hell, as dark as night.
