How do the setting and her daily life reinforce the idea expressed in the line "I am all longing" from the Wife's lament?
The line "I am entirely longing—" from "The Wife's Lament" is reinforced by the circumstances and setting in which she lives. Her husband, whom she loved and felt a great affinity for, has left her. He has ordered her to stay behind and live in a cave in a grove, and she feels betrayed because they had pledged their undying love to one another.
She is surrounded by the graves of former friends in a sort of wasteland. Every day she weeps because of her abandonment and isolation. She thinks of her absent husband and reflects on the idea of people who are separated from the ones they love—she seems to express that she hopes that he is suffering, too. She has concluded that he has plotted against her. She is "all longing" because she pines for what she does not have—and likely never has had.
