NEW YORK (AP) — Dwayne "The Rock" Johnson has discussed his battle with depression. Mariah Carey recently revealed she has bipolar disorder. And "Deadpool" superstar Ryan Reynolds has acknowledged dealing with anxiety disorder.

As the stigma surrounding mental illness has declined in recent years, so has the reluctance many have had to discuss their own mental health issues, including celebrities. It's become the new norm for stars to divulge vulnerabilities once kept closely guarded.

Ryan Reynolds says talking about his anxiety disorder has helped, especially in an age that he described as "toxic masculinity."
