There are a couple of different types of conflict going on in the story. I believe that the primary conflict is Man vs. Society. The protagonist is living in a society (and further, a home) where she is not treated as an individual. She is controlled by both her brother and her husband as they attempt to do what they believe is best for her as a sick woman. They do this without any real consideration paid to what she wants. They force her to accept the idea that her own thoughts do not represent reality and that the only opinions that can be trusted are those of the men who are caring for her, regardless of what she wants or how she feels. TheMan vs. Self conflct stems from the Man vs. Society conflict. As society is telling her that she is crazy, cannot trust her own thoughts, and must give complete control in her life over to the men, she struggles to maintain her sanity and determine for herself what is real. She becomes increasingly aware of her powerlessness and, as she tries to repress this newfound awareness, she descends further.
