Catherine Zeta-Jones: Her History of Mental Illness

Catherine Zeta-Jones is currently in a treatment center receiving help to control her bipolar II disorder, an ongoing struggle she has been candid about over the years.

The 43-year-old Oscar-winning actress went public with her mental health battle in 2011. After her husband, Michael Douglas, received the good news that his Stage IV throat cancer was gone that January, she couldn't fight a lingering depression. In April of that year, she checked into a mental health facility in Connecticut and during her five-day stay there, she was diagnosed with bipolar II disorder, a mental illness marked by prolonged periods of depression alternating with episodes of mild mania.

"This is a disorder that affects millions of people and I am one of them," the actress, told People at the time. "If my revelation of having bipolar II has encouraged one person to seek help, then it is worth it. There is no need to suffer silently and there is no shame in seeking help."

Zeta-Jones first began suffering from anxiety several years earlier -- around the time she was filming 2004's "Ocean's Twelve" and she was also dealing with a stalker. However, she tried to fight it, telling Britain's Sunday Times in 2010, "Being negative isn't good for my personality. I don't just bring myself down; I bring everyone around me down. It's like a dark cloud. 'Uh-oh, here we go,' and I have to snap out of it."

While Zeta-Jones seemed to be comfortable going public with the disorder, in December 2012 she seemed a bit less so.

“You know what, I’m sick of talking about it because I never wanted to be the poster child for this,” Zeta-Jones told "Good Morning America." “I never wanted this to come out publicly. It came out. And so I dealt with it in the best way I could and that was just say, ‘Look, hey, I’m bipolar.’”

“Everyone has things going on and we deal with them the best we can,” she continued. “We can’t jump from the rooftops shouting, you know, about, ‘I have this, look at me, victim.’ No. We all have issues in life and I’m really happy that I have great friends, great support, and that’s all I can do.”

And she has her support system in place now that she's in treatment again. It was announced on Monday -- after her husband attended the White House Correspondents' Dinner by himself -- that she is again seeking help in an in-patient facility.

"Catherine has proactively checked into a health care facility," a rep for the actress said in a statement Monday night. "Previously Catherine has said that she is committed to periodic care in order to manage her health in an optimum manner."
