Jennette explains all of this in I'm Happy My Mom Died in harrowing detail, just as she describes what transpires when the dream ultimately materialises. She became well-known after being cast in the iCarly TV show. While Jennette is plagued with anxiety, guilt, and self-loathing, which manifests as eating problems, addiction, and a string of disastrous relationships, Mom is overjoyed, emailing fan club moderators and getting to know the paparazzi by name ("Hello Gale!"). As soon as she joins Ariana Grande in the lead role of the iCarly spinoff Sam & Cat, her mother passes away from cancer, making these problems even worse. Finally, after learning about therapy and giving up acting, Jennette starts to rehabilitate and makes a life-changing decision.
