Despite her success and happy appearance on television, McCurdy previously told PEOPLE that life with her mother Debra was far from perfect.

"My earliest memories of childhood were of heaviness, and chaos," McCurdy told PEOPLE ahead of her memoir release. In particular, "My mom's emotions were so erratic that it was like walking a tightrope every day. The mood fluctuations were daily."

The overwhelming pressure of keeping up this front led the actress to suffer from eating disorders, addiction, and more. Her mother was undergoing challenges of her own at the same time; when McCurdy was 2 years old, Debra was diagnosed with breast cancer. She died in 2013.

In the memoir, McCurdy claimed how her mother’s control extended beyond forcing her to continue acting.

Debra's alleged control went as far as "wiping my butt" at eight years old, McCurdy recalled in the memoir, adding that her mom said she "needs to do it until I'm at least 10."

In addition, McCurdy said Debra regularly performed breast and "front butt" exams on her to check for potentially cancerous lumps and bumps. "By the time the exams are done, a huge wave of relief washes over my whole body," she penned. "I usually realize that's the first time I've felt my body since the exam started."

She also noted that her mother gave her showers, too, in addition to — and at the same time as — her brother Scottie, who was almost 16. When he asked to shower himself, McCurdy wrote: "Mom sobbed and said she didn't want him to grow up so he never asked again after that."
