Why does ellie have to write everything down in twtwb?

In "The Things We Bury," Ellie writes everything down to cope with her traumatic experiences and to maintain a sense of control in her chaotic life. Writing serves as a therapeutic outlet, allowing her to process her emotions and memories. It also helps preserve her thoughts and feelings in a world that often feels overwhelming and uncertain. Ultimately, her written Words become a lifeline, connecting her to her past and guiding her toward healing.
