Do you agree or disagree that the narrator's wouldn't have gone crazy if she hadn't been locked in the nursery?

At the beginning of the story, it is unclear if the narrator is actually insane. If she is truly ill, then it is likely that she would have gone mad even if she had not been confined to the nursery. If the narrator is not ill at the start of the story, then the mere confinement and inactivity could have been sufficient to cause a mental breakdown. Either way, the yellow wallpaper serves as an obvious catalyst for her mental deterioration, but we do not know if it is merely a symptom of her insanity or the cause.
