(Image via Threads)Hayden’s father, Skip Panettiere, told ABC News:“It is with profound sadness that we share the tragic passing of our beloved Hayden. She was an incredible light and a force of nature who brought immeasurable love and joy to all who knew her -- and to the millions who watched her onscreen. We ask for privacy as our family takes time to process this unimaginable loss.”Her death comes three months after she wrote a tell-all memoir called This Is Me: A Reckoning. The synopsis for her book reads on her website:“A rare and intimate glimpse into her life behind closed doors, opening up about postpartum depression, addiction and recovery, trauma, domestic abuse, and loss.”Here’s what Hayden Panettiere said in the months before her passingHayden Panettiere sat down with Jay Shetty in May promoting her memoir This is Me: A Reckoning, in what was one of her final interviews. She spoke about struggling with “darkness” for years and personal challenges, before adding she had a “lot more life to live.”“I finally feel like I have shaken off all of this darkness and this negativity. I’ve closed one door and another door is opened… I can feel all the exciting possibilities. I feel like I have a lot more life to live,” the Heroes actress said.Hayden Panettiere was hopeful about “exciting possibilities” in both her career and personal life and said she’d finally moved on from years-long negativity. She also opened up about grieving her brother Jansen’s untimely demise, struggling with postpartum depression and motherhood, letting her ex-fiancé have full custody of their 11-year-old daughter, and mental health and alcoholism struggles. At one point, she confessed feeling “sheer terror” during her early fame.“I think there’s been this very common misconception that I just gave up my child. That could not be farther from the truth… I was in a horrible cycle for years of battling depression and anxiety and alcoholism and substance abuse and was just trying to find my way back, my way out of the darkness,” Hayden explained.In her book, the Nashville actress wrote about her struggles with childhood stardom and claimed she was “groomed” like a “little soldier.” An excerpt from the book reads, according to spokesman.com:“Grown-ups gave me positive attention when – as an actor – I failed, got sick, screamed and cried, killed, grieved, and suffered. Reality merged with my imagination and burrowed into my core memories, where all my shame and trauma live. I’ve often wondered whether – unintentionally – I’ve brought on my traumas because I’m wired to think they’re good for me.”In a July cover story for parenting outlet Momé, Hayden Panettiere stated:“I’m a work in progress – we all are. I take each day as it comes. I’m doing the work, and I’m doing my best… I’ve been able to put her first no matter how I’ve felt or what I’ve experienced. One day she’ll understand my story, and why I wasn’t able to be with her all the time.”She shared a positive message for fellow mothers:“You’re stronger than you know. And you’re going to be just fine.”Speaking at a book signing/panel for her memoir three months ago at L.A.’s Harmony Gold Theater, Hayden Panettiere said:“So many people have come up to me within the industry and outside of the industry and shared their stories with me and said, ‘Because you’ve talked about your mental health, it gave me the courage to be honest about mine and get myself help and you saved my life.’ I was like, this is worth it. I can hopefully leave the world a better place than I found it.”Hayden Panettiere appeared on Good Morning America in 2022 and said that the years after her role as aspiring country artist Juliette Barnes on CMT/ABC musical soap opera Nashville had been “difficult,” as were the years before. As a result, she needed a “break.” During that time, she also got herself into rehab. During that time, she also got herself into rehab.Scream star even compared her life to her onscreen character in her memoir and how the doctors told her she’d be “dead within five years” if she didn’t stop drinking.“Not my child, not my job, and not the rest of my life. I needed a drink to function,” Hayden Panettiere wrote.In another excerpt, she continued:“Juliette Barnes had postpartum depression, and alcohol and pill problems, and a divorce on the horizon. She was erratic, an absentee mother, and fought with everyone, including her fans. Every time I read the day script, it was like I was looking in a funhouse mirror, seeing a distorted reflection of myself. I can’t tell you how lost this made me feel,” she wrote.In 2023, Hayden Panettiere told Women’s Health Magazine:“I was the one who put myself in the first treatment center. I was drowning.”Hayden Panettiere welcomed her only child, Kaya Klitschko, in 2014, with Ukrainian former heavyweight champion Wladimir Klitschko.Meanwhile, her brother and fellow actor Jansen Panettiere died from “cardiomegaly (enlarged heart), coupled with aortic valve complications” in Nyack, New York, in February 2023. He was 28.
