In Jeffrey Eugenides' "The Marriage Plot," the author explores the deep and persistent nature of depression. He likens it to a bruise that never fully heals, emphasizing its lasting impact on an individual's mental state. This metaphor illustrates that depression cannot simply be willed away or removed; it is an enduring presence that one must navigate cautiously, as it can be easily aggravated.

The complexity of dealing with depression is highlighted through the notion that it creates a sensitive area within the mind. Just as a physical bruise requires care to avoid further pain, those suffering from depression must be vigilant about their emotional well-being and trigger points. This analogy captures the essence of living with a mental health condition that is both subtle and profound, affecting everyday life.
