“Grey’s Anatomy” star Justin Chambers announced on Friday that he’s exiting the hit series after 15 years to “diversify my acting roles and career choices.”

Sources exclusively told Page Six that the star was also recently addressing some mental health issues at the same luxury facility where Selena Gomez and “Game of Thrones” star Kit Harington have been patients.

A source told Page Six that Chambers spent time at Privé-Swiss in Connecticut before leaving Wednesday to fly back to LA.

“Justin has been at [Privé-Swiss] for stress and life coaching. He has been seen in the area at different places over several weeks including at a restaurant at Old Saybrook — where he was nice and chatted to other diners, but looked very thin.”

A second source told us that, “Justin was at Privé-Swiss being treated for stress, depression and life-coaching. There is a lot going on with [‘Grey’s Anatomy”] behind-the-scenes right now.”

In a statement to Page Six, Chambers said: “There’s no good time to say goodbye to a show and character that’s defined so much of my life for the past 15 years. For some time now, however, I have hoped to diversify my acting roles and career choices. And, as I turn 50 and am blessed with my remarkable, supportive wife and five wonderful children, now is that time.”

He added, “As I move on from ‘Grey’s Anatomy,’ I want to thank the ABC family, Shonda Rimes, original cast members Ellen Pompeo, Chandra Wilson and James Pickens, and the rest of the amazing cast and crew, both past and present, and, of course, the fans for an extraordinary ride.

A rep for the facility said: “Privé-Swiss does not comment on clients, past or present.”

More than a decade ago, Chambers opened up about a longtime sleep disorder that led him to check into the same UCLA Medical Center where Britney Spears was once treated.

He told People in 2008: “It’s a biological sleep disorder. Your mind keeps racing, and your body is tired. It wants to go to sleep, but it can’t.”
