William Shakespeare said this quote

“ My love is as a fever, longing stillFor 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,Angry that his prescriptions are not kept,Hath left me, and I desperate now approve,Desire his death, which physic did except.Past cure I am, now reason is past care,And frantic-mad with evermore unrest;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. ”
