Bruce Willis's daughter Tallulah Willis reveals 'life changing discovery'

Tallulah Willis disclosed this week that she received an autism diagnosis last summer, stating on Instagram that the news "changed my life."

Willis, the youngest child of Bruce Willis and his ex-wife Demi Moore, shared an old family video to Instagram on Saturday that shows her messing with her father's ear as a little toddler while walking the red carpet.

“Tell me your [sic] autistic without telling me your [sic] autistic,” Willis captioned the post. In the comments section, she elaborated: “Actually this is the first time I’ve ever publicly shared my diagnosis,” she wrote. “Found out this summer and it’s changed my life.”

Willis has already openly discussed her health before making her disclosure. She discussed her battle with anorexia, which she claimed to have battled for four years, in an essay that was published in Vogue last summer.

“After getting sober at age 20, restricting food has felt like the last vice that I got to hold on to,” she wrote.

“When I was 25, I was admitted to a residential treatment facility in Malibu to address the depression that I had lived with through my adolescence. It was a largely therapeutic experience; for the first time, I grieved the 15-year-old misfit me, the ugly duckling. I was also diagnosed with ADHD and started on stimulant medication, which was transformative. I felt smart for the first time, but I also started to enjoy the appetite-suppressant side effects of the meds. I saw a way to banish the awkward adolescent in favour of a flighty little pixie.”

Willis discussed her mental health during her father's deterioration and her diagnosis of frontotemporal dementia in the same post.

“I admit that I have met Bruce’s decline in recent years with a share of avoidance and denial that I’m not proud of,” she wrote. “The truth is that I was too sick myself to handle it.”

Later, she added, “Now that I’m feeling better I ask myself, How can I make him more comfortable? It wasn’t easy growing up in such a famous family, struggling as I did to find a patch of light through the long shadows my parents cast. But more and more often I feel like I’m standing in that light.”
