I hadn't heard of "Tell Me I'm Worthless" before now, and An Outcry started development in 2019, a good bit before the book's release in 2021. Also, that line itself is an allusion to the opening of Shirley Jackson's "Haunting of Hill House" ("No live organism can continue to exist sanely under conditions of absolute reality").

In short: It's a coincidence, but a pretty interesting one. Thanks for bringing that book to my attention!
