Erin Moriarty is opening up about her Graves’ disease diagnosis and the devastating impact it had on her life in a deeply personal new essay.
The 31-year-old The Boys star wrote an emotional essay for Time, published on Thursday (May 21), in which Erin detailed discovering “the heartbreaking way that a medically confused woman is rarely considered credible.”
“My memory was failing me. My body felt unfamiliar. My emotional presence, something I had always protected and valued fiercely as an actor, became increasingly difficult to access,” she wrote.
Erin said her symptoms became significantly more noticeable in September 2023. She was “sleeping through every alarm” and often felt so exhausted that she was incapacitated.
“On weekends, I would sleep 19 hours (or more) straight. The mood swings I had experienced years earlier intensified. My hands and feet became so weak and numb that walking began to feel dangerous. I developed heart palpitations and persistent urinary pain,” Erin wrote.
The Jessica Jones actress explained that she was filming the final season of The Boys while her neurologist searched for answers. Erin said she struggled to learn “even simple lines” because of worsening short-term memory issues and symptoms of “cognitive decline.”
“I was going through the physical hell of chronic illness on a public stage,” Erin continued. “Doing it in private is emotionally damaging enough, but to have my physical symptoms be speculated about, trivialized, and dismissed was devastating.”
Erin finally received her Graves’ disease diagnosis in May 2025 and said the moment helped her begin rebuilding her life because it “gave shape to the chaos.”
“It gave language to suffering that had gone on for years. It gave me an answer,” Erin shared.
While Erin’s physical health slowly began improving, her mental health continued to suffer. The actress revealed she was hospitalized “following a severe mental-health crisis” in August 2025.
“I had been hormonally dysregulated, cognitively impaired, and psychologically untethered for so long that recovery didn’t bring me peace,” she added.
“It brought me clarity,” Erin continued. “And for me, clarity arrived carrying grief. Grief for the time I could not get back. For what this illness had taken from me professionally, creatively, relationally, psychologically. I spent at least two years of my life physically present but mentally unreachable. My grief hit me so hard that there was a moment I was unsure I could carry it.”
At the end of her essay, Erin urged others to pay attention to their symptoms, hoping her experience could help someone else find answers sooner.
“I hope the transparency surrounding my symptoms can help even one person catch their illness earlier than I caught mine. The body speaks long before it screams. Listen to yourself before your body is forced to scream loud enough for the world to hear it, too,” she concluded.
