The "super cool older sister" voice was welcomed at first, especially for this season of my life, but got somewhat grating about halfway through. I did love the raw honesty presented in the novel and it was validating to know someone could also recover from an emotionally dysregulated, messy life. There's not a lot of new material in the self-help parts and seems to be largely dependent on active journaling practices, but again if you want to be validated on your self help journey and need to be told that everything will be okay eventually then this is a great read.
