 Jennette McCurdy defends the title of her book, "I'm Glad My Mom Died": 'Sincerely,' I say.

Jennette McCurdy, who claims she was abused by her late mother, Debra, stands by her decision to title her memoir "I'm Glad My Mom Died."

"I understand that it's attention-grabbing, but it's also something that I mean sincerely," she said of the title on "Good Morning America" on Wednesday.

The "iCarly" alum, 30, explained that she wasn't using the title "flippantly" and that she believes people who have been abused will understand the point she's trying to make.

"While the reaction has been mixed, I really appreciate the outpouring of support from so many people," she said.

"I believe that anyone who has experienced parental abuse, as well as anyone with a sense of humor, understands this title."

McCurdy went on to say that she's "not so concerned" with other people's opinions, noting that "this book is not for them."

McCurdy also admitted that she misses her mother, who died of cancer in 2013. However, she admitted that if her mother was still alive, she would not have written her memoir because her "identity would still be dictated by her." " My grief for my mother used to be very complicated. "I'd be angry and confused about why I was angry because I was grieving for her," McCurdy explained.

"I felt like she didn't deserve my tears and sadness because she was abusive, but it simplified in such a way that it now feels like I can just miss her." I believe that is only possible because of the healing that occurred as a result of the book's writing."

McCurdy detailed the abusive behavior her mother allegedly displayed while she was growing up and during her rise to fame while starring in "iCarly" and the spinoff series "Sam & Cat" in her tell-all book.

"I start shrinking by the week as Mom and I team up every night to count our calories and plan our meals for the next day." We're keeping me on a 1,000-calorie diet, but I've come up with the brilliant idea that if I only eat half my food, I'll only get half the calories, which means I'll shrink twice as fast," McCurdy wrote in her book (via ET).

Jennette McCurdy and her mother

She weighs me and measures my thighs with a measuring tape every Sunday. After a few weeks of our routine, she hands me a stack of diet books, which I devour... "Every day, I weigh myself five times."

McCurdy claimed that when a doctor suggested she might have anorexia, her mother denied any knowledge of her eating habits. She also revealed that her weight had dropped so low that she had to use a booster seat in the car at the age of 14.

The actress also claimed that her mother would bathe her every time she had to shower and perform "a breast and 'front butt' exam," and that her mother would even shave her daughter's legs when she was 16 years old.

She claims she wants to make sure I don't have any strange lumps or bumps that could be cancer. "I say okay because I don't want cancer, and since Mom has it, she'd know if I did," she wrote.

"When Mom is taking exams, I usually try to think of Disneyland... When the exams are finished, I usually feel a huge wave of relief wash over my entire body, and I realize it's the first time I've felt my body since the exam began."

McCurdy went on to say that as her fame grew, her mother began to resent her.

I never imagined that fame could put such a schism between Mom and me. She desired it. And I wanted it for her. "I wished for her happiness," she wrote.

"But now that I have it, I see that she is content and I am not." Her joy came at the expense of mine. I feel cheated and taken advantage of. When I look at her, I just hate her. And then I feel bad about myself for feeling that way."

McCurdy also recalled the time her mother discovered she had begun dating but was not yet sexually active. In her book, she describes her mother as a "FILTHY LITTLE LYING W—E" and "nothing more than a little S-T, a FLOOZY, ALL USED UP."
