In her reflections on marital issues, the author compares such discord to a persistent, low-grade fever. This metaphor illustrates how ongoing relationship troubles can subtly disrupt an individual's overall well-being and functioning. Rather than a severe crisis, the strain from marital problems affects daily life in a less obvious but persistent manner.
