Hamlet and Suicide
This is a good example of how Hamlet thought of solving his situation. Hamlet struggles with this idea because he believes that suicide is a sin. He later speaks in a manner with some underlying ability of moving on.
"To be, or not to be: That is the uestion: Whether 'tis nobler in the mind to suffer/The slings and arrows of outrageous fortune, Or to take arms against a sea of troubles, And by opposing end them" (697).
Hamlet again speaks of death but this time it does not seem that he is so firm on suicide being the only answer. This story from Shakespeare seems to be the opening into showing one's emotions on the inside without being afraid to do so.
Oedipus and Suicide
Oedipus is using light to explain that he does not want to live anymore. He sees himself as such a disgrace that he gouges out his own eyes. He did not want to live anymore after he found out that the prophecy came true, his wife committed suicide, and his children's lives were ruined because they were inbred.
