Alicia Keys has revealed the profound hurt caused by her father's abandonment, detailing in a new documentary how she wrote him a letter at age 13 telling him to stay out of her life. The Grammy Award-winning singer stated that she told Craig Cook, who left when Keys was two years old, "I don't want anything. That's the only way you can make me happy."

The documentary, "Alicia Keys: Girl From Hell's Kitchen," explores the singer's childhood in Manhattan's Hell's Kitchen, where she was raised by her mother, Terria Joseph, who worked multiple jobs to support her daughter's musical ambitions. Cook, in the film, acknowledges his immaturity at the time of Keys's birth in 1981, admitting he was unable to take on the responsibility of fatherhood.

Keys described her father's absence as a recurring pattern of showing up only to disappear again. "My father wasn't there when I was born… on that evening Mommy lay in bed wondering how she would come up with the money for the hospital bill," Keys said in the documentary. Her mother sacrificed her own ambitions to provide piano lessons for her daughter.

Despite growing closer to her paternal grandparents, Keys harbored anger over her father's repeated absence. She recalled promises of meetings with her father that were consistently delayed or deferred. "I was so furious, I was so over it, I didn't care any more and I wanted him to know it, I wanted everybody to know it," she stated.

Cook expressed that reading the letter is still painful for him. The estrangement continued until Keys began working on her Tony Award-winning Broadway show "Hell's Kitchen," which draws loosely from her life. Keys found writing the father figure for the musical's character to be "a big vehicle for healing."

"My grandmother's dying wish was that she wanted family unity," Keys shared, explaining that this sentiment prompted a shift in her perspective. "Craig didn't have to be my dad but he was my father."

Cook also spoke of mutual growth enabling their current relationship. "That's who I was then, that's not who I am now," he said in the film, reflecting on his past.

The documentary "Alicia Keys: Girl From Hell's Kitchen" premiered at the Tribeca Film Festival.
