Landmark Social Media Trial: Woman Testifies Instagram and YouTube Fueled Mental Health Crisis
Los Angeles, CA – Kaley GM, a 20-year-old California resident, testified on Thursday, February 26, 2026, that her extensive use of Instagram and YouTube as a child exacerbated her mental health issues, including depression, body image problems, and self-harm. The case, being heard in Los Angeles Superior Court, is a landmark trial that could set a precedent for holding social media companies accountable for the addictive nature of their platforms and their potential harm to young users.
Addiction Began in Childhood
Kaley GM recounted becoming addicted to YouTube at the age of six, stating, “I was young and I spent all my time” on the platform. She described an inability to separate herself from the apps, even when experiencing negative consequences like bullying on Instagram. “If I was off, I would just experience like I was missing out,” she testified. She accessed Instagram at age nine, circumventing parental controls on her phone.
Mental Health Struggles
The plaintiff detailed how her social media use contributed to the development of social phobia and body dysmorphia. She shared an Instagram video of herself as a pre-teen apologizing to her followers for her appearance, saying, “I’m sorry for being so ugly, I look so fat in this top.” Her lawyer presented dozens of selfies taken over the years, noting that “almost all were taken with a filter.” Kaley began experiencing depression and suicidal thoughts around age 10, and engaged in self-harm.
Defense Focuses on Family History
During cross-examination, lawyers for YouTube (owned by Google) and Meta (owner of Instagram) sought to portray Kaley’s mental health struggles as stemming from a chaotic childhood and a dysfunctional family. They highlighted her parents’ divorce at age three, her father’s frequent criticism of women’s weight, and a sister’s prior suicide attempt. Recordings of her mother yelling at her were also presented. Kaley acknowledged having attention deficit disorder, which was diagnosed later in life, and admitted her mother sometimes physically disciplined her due to misunderstandings related to her learning disability.
Broader Implications of the Case
The trial is expected to last until late March, with the jury tasked with determining whether Meta and Google knowingly designed addictive apps that harmed Kaley GM’s mental health. Meta CEO Mark Zuckerberg testified last week, defending his company’s practices. The outcome of this case is being closely watched, as it could pave the way for numerous similar lawsuits against social media companies, mirroring legal battles waged against the tobacco industry in the 1990s. TikTok and Snapchat have already reached financial settlements with Kaley GM to avoid trial.
