Your profusion makes me saving; and if you lament over him much longer, my heart will be as light as a feather.

– Jane Austen

Pride and Prejudice, Chapter 40. When Jane joins Elizabeth in lamenting over how badly Darcy was treated, Elizabeth feels a sense of relief as her sister helps share her distress. Burdened by guilt over her misjudgment of Darcy, Elizabeth uses a simile to compare her heart to a feather. Jane and Elizabeth are two of the closest Bennet sisters and are very supportive of each other.
