Watch: Selena Gomez Feels "Freedom" After Sharing Her Mental Health StrugglesRobbie Williams is facing a new health challenge. The "Angels" singer shared that he was diagnosed with Tourette syndrome, a neurodevelopmental disorder characterized by rapid, repetitive and involuntary muscle movements or sounds called "tics." For Robbie, however, those involuntary tics aren't external but internal. "I've just realized that I have Tourette's, but they don't come out," the 51-year-old explained during the Oct. 2 episode of the I'm ADHD! No You're Not podcast. "They are intrusive thoughts that happen." The Take That alum-who shares children Theodora, 12, Charlton, 10, Colette, 6 and Beau, 5, with wife Ayda Field-went on to describe the moment he realized he might be afflicted with the syndrome. "I was just walking down the road the other day and I realized that these intrusive thoughts are inside Tourette's," Robbie said. "Not only that, you would think that a stadium full of people professing their love to you would work [as a distraction], but whatever it is, inside me, cannot hear it. I cannot take it in."photosCelebrity Health ScaresAnd that's not the only health concern the musician has been dealing with as of late. Robbie also shared that he believes he may have autism, a mental disorder that is characterized by challenges with social skills, repetitive behaviors, speech and nonverbal communication, according to Autism Speaks. "It turns out I'm not," the musician shared, revealing that he took an online test to reach the conclusion. "But I've got autistic traits. It's around social stuff-it's about interaction."Joe Schildhorn/BFA.com/ShutterstockThat's why Robbie hopes to see a medical professional about his theory soon, insisting that a more official diagnosis would give him an "understanding of why I feel so uncomfortable in my skin." "When I'm in bed, that's my comfort zone. Anywhere outside of that bed is my discomfort zone," he continued. "It's getting better. It was awful, horrendous through my 20s, bad through my 30s, my 40s started to get better and I'm on an upward curve, but I'm still uncomfortable in my skin."

"I know that I hated my body," Penn told The Guardian in April 2025, "and simply wanted a different one." In response to the weight he gained following his parents' divorce, he added, "There was just a period where, coming out of depression and isolation, I was jumping wilfully into, but also being thrust into, this world where the more conventionally beautiful I seemed, the more successful I might be, the more value I might have." Despite the mental struggles, though, Penn credited his ability to persist to his spirituality. "That is what allowed me to persevere through the disillusionment, all the things I'd been grappling with," he explained, "and then come back to it all, but with hopefully some kind of inner transformation." John Salangsang/ShutterstockEliza CoupeThe Scrubs alum has been vocal about her past difficult relationship with food. "Some may call it an eating disorder, I just call it my life," she said on the The Funny Thing Is podcast. "My drug of choice was always food. I did crazy s--t with it." She added, "I would over-exercise, and there was a sprinkle of bulimia in there." Though she has confessed her struggles with her diet, she has also shared her progress with her health and fitness goals. "When I was 23, I cut all sugar out of my diet, quit drinking, and found yoga and breathing and stretching," she told Bon Appétit in 2017. "That's the best Ritalin you could give anyone." She continued, "I'm an actress with food issues and body image issues-that's real. But I'm trying to heal that part of myself and also handle my physical issues naturally by putting the best things into my body."River Callaway/Variety via Getty ImagesCandace Cameron BureThe Full House alum reflected on her mental health journey and navigating her battle with depression. "It's very difficult to speak out about it, even to your most trusted people," she shared on her Candace Cameron Bure Podcast. "At least for me, I feel like I should be strong enough to overcome that and then it feels so weak."David Fisher/ShutterstockBillie EilishThe Grammy winner has been very open about how she protects her energy, such as ignoring haters on social media, while also sharing her advice for those who may need help. "When people ask me what I'd say to somebody looking for advice on mental health, the only thing I can say is patience," she told Vogue. "I had patience with myself. I didn't take that last step. I waited. Things fade."Jamie McCarthy/Getty ImagesKaty PerryWhile everyone was trying to make the best of socially distancing to slow the coronavirus pandemic, the "Firework" artist got
