Answer:
Daisy's wedding is described in the novel, and it isn't difficult to see that she is rather upset just before the wedding takes place. She gets a letter from Jay Gatsby that disturbs her, as she is reminded that she rejected the man she really loved in favor of a wealthy man.
Step-by-step explanation:
Daisy fell in love with Lieutenant Jay Gatsby, who was stationed at the base near her home. Though she chose to marry Tom after Gatsby left for the war, Daisy drank herself into numbness the night before her wedding, after she received a letter from Gatsby.
