The common misconception that "anyone who tries to kill him/herself must be crazy" is disproved in literary works about suicide.

 

In 'night Mother, Jessie wasn't crazy. She even said she "waited until i felt good enough, in fact."  As the literary critic, Lisa J. Mcdonnell states, "Although many argue that her death is merely an act of desperation, Jessie's decision to take her own life displays a new confidence in herself."

 

In Richard Cory, Richard Cory was the man everyone wanted to be: rich, charming, intelligent.  If he were crazy, his suicide would've shocked no one, which is not the case since he shocked the entire town. 

 

In Many Rivers To Cross, June Jordan also explains how her mother's death came as a surprise to them.  Even her father couldn't tell whether or not she was dead.
