In "The Yellow Wallpaper," writing is a healthy means of self-actualization denied to the narrator. The narrator portrays writing positively in the story, believing that it will help her depression. Others around her, however, heavily disapprove of her writing, believing it to be a tiring activity.
In "The Yellow Wallpaper," the narrator’s rich imagination might have found a productive and healthy outlet in her writing, but being forced to repress her imagination instead leads her to madness.
