Colton Haynes recently opened up about a problem he's battled for more than 15 years, which has also landed him in the hospital: Anxiety.
The 27-year-old Arrow actor and former Abercrombie & Fitch model posted a series of tweets about it late on Tuesday, after posting a link to a story about a Swiss medical study titled, "Mitochondrial Function in the Brain Links Anxiety With Social Subordination."
"For those of you who are suffering with intense anxiety...ur not alone," he said. "It's been a constant struggle for me since 5th grade. It's a battle."
"Anxiety had put me in the hospital a countless amount of times," he added. "Whether it be fainting, hyperventilating, or seizures...I've been through it. Just know ur not alone & it affects more ppl than you would ever know. We can overcome this. We can fight thru it & will."
