Nora suffers greatly from inner conflicts through the story. The first is the want to please in order to justify her role in the family. She is a mother and a wife, but she has surrendered to the diminutive role her husband has bestowed upon her: That of an entertainer. She is innately struggling with the need to be a useful individual as she desires to be both wanted and needed. She did the same thing with her father when she took care of him, and with her husband when he was ill and she had to do the business transaction with Krogstad.
Yet, she is neither wanted nor needed: She is more like a fixture that must operate under the mandates of what society expects from women. Therefore, she is further tormented by not being understood in her efforts to please and be liked.
Furthermore, she is being bullied by Krogstad, and her whole life is in jeopardy: All for trying to help and be useful, loved, and needed.
In the end, Nora had to endure the humiliation to be thrown in her face all her efforts as a silly way to react to problems. This was done by her husband, and was what ultimately led her to her final shock, and eventual abandonment of her family, and of her former self.
