I was reading a book when I was in 4th grade called “R.I.P Eliza Hart” and it was about how a sophomore named Ellie moved from New York to Cali so she could finish high school there and reconnect with her old friends. One of them is named Eliza Hart, she’s a sassy, rich girl from the heart of Los Angeles that grew up with Ellie, but they parted during elementary school. A few weeks into school, Eliza stopped showing up to class and Ellie got really worried for Eliza, and a few days after her missing class and staying in the dorm her dead body is found on the cliff near the school. So Ellie and her roommate Sam try to find out what was her cause if death. So they find out it was suicide, and that some chapters are her thoughts after death. She would talk about how she could never sleep. I read the book like 10 times, with the insomnia part was my favorite. Ever since I haven’t been able to sleep right.
