"The weight that hangs upon our eyelids - is of lead"

In this quote, Mary Chesnut is describing the heavy problem that weighs down on our minds and bodies. She compares this weight to lead, a dense and heavy metal. This weight is so heavy that it triggers our eyelids to sag and makes it difficult for us to keep our eyes open. This might be interpreted as a metaphor for the weight of our concerns, worries, and responsibilities that can be frustrating and stressful. Chesnut's use of imagery efficiently communicates the idea that this weight is not easily raised and can be a constant battle for us.
