Which expression best correlates with feeling overwhelmed?

The expression that best correlates with feeling overwhelmed is "shattered." This term conveys a sense of being broken down or exhausted, often as a result of overwhelming stress or emotional strain. When someone feels overwhelmed, they might feel as though they are unable to cope with the demands placed upon them, leading to feelings of being utterly spent or "shattered."

In contrast, the other options represent feelings that are quite the opposite of being overwhelmed. "Enlightened" suggests a state of clarity and understanding, which is far removed from feelings of stress. "Content" indicates a sense of satisfaction and peace, which would not align with feelings of being overwhelmed. Similarly, "relaxed" implies a state of calm and ease, again distancing itself from the notion of being overwhelmed. Therefore, "shattered" accurately reflects the emotional and physical toll often associated with feeling overwhelmed.
