Colton Haynes of “Arrow” fame is speaking up for those who suffer from intense anxiety.

The actor who played the titular star Stephen Amell’s sidekick Arsenal on the CW series, took to Twitter on Tuesday night after sharing an Upvoted article about the effects of anxiety on social status and sent a series of messages about his personal struggle.

“For those of you who are suffering with intense anxiety...ur not alone. It’s been a constant struggle for me since 5th grade. It’s a battle,” the 27-year-old wrote, adding, “Anxiety had put me in the hospital a countless amount of times. 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,” he said.

Despite his memorably outrageous Halloween costumes and appearances in blockbusters such as “San Andreas,” the former “Teen Wolf” star said he quit jobs because of his anxiety and “flaked on social events, family gatherings, birthdays, important movie/work tests.”

The actor left MTV’s “Teen Wolf” after about two seasons, then started a recurring role on “Arrow.” He became a series regular in the second and third seasons of the DC Comics-inspired series before exiting at the end of last season when his contract was up. It’s unclear if his anxiety contributed to his departures.

Haynes emphasized that anxiety is “a serious problem” and urged followers to “be there for those who struggle with anxiety & realize its a serious disorder.

“Its not a case of ‘being dramatic’...its a life long struggle,” he tweeted, adding, “Love those suffering. Anxiety has caused me to be extremely agoraphobic & livin in constant fear of leavin my house at times. Ur not alone.”

The Upvoted article noted that 40 million adults across the U.S. suffer from anxiety disorders, which are considered the most common mental illnesses in the nation.
