William Faulkner said "The only thing worth writing about is the human heart in conflict with itself." I agree with this statement because self conflict is the most difficult type of conflict to resolve; one has to be his/her own mediator while fighting two battles at the same time. Eugene O'Neill's Long Day's Journey into Night gives perfect examples of this through Mary Tyrone's conflict with being a morphine adict and a very unhappy wife. O'Neill uses irony to portray the disharmonic struggles she goes through.
             Mary Tyrone is a mother of two and ironically a morphine addict as well. Her main disagreement takes place between her addiction and her desire to be a good mother and role model for her alcoholic sons, Jamie and Edmund. She is not able to give them the attention they need because of her obsession with morphine.
             Once they're done they make you do other things until at last
             everything comes between you and what you'd like to be,
             and you've lost your true self forever.
             Mary, while talking about the doctors who originally 'prescribed' her with morphine, admits that the morphine disables her to do what she's like to such as taking care of her grown up children. Instead, she aids to her addiction, which takes away from being a good mother.
             My father... spoiled me. He would do anything I asked him. He would have
             sent me to Europe to study after I graduated from the Convent. I might have
             none-if I hadn't fallen in love with Mr. Tyrone. Or I might have become a
             nun. I had two dreams. To be a nun, that was the more beautiful one. To
             become a concert pianist, that was the other one.
             Mary has so many plans and ambitions but the fact that she married a frugal man who wouldn't pay for a qualified doctor gave way to her morphine addiction. She is in denial of the fact that Edmund has consumption; she refuses to get it treated...
