Catherine Zeta Jones is reportedly seeking medical help for her bipolar II disorder, and has checked into a medical facility already.

The Academy Award winner is reportedly seeing medical attention for her illness and checked into a medical facility Monday for a complete 30-day program to treat her bipolar II.

Celebrity news websites reported that sources close to the actress have confirmed that the treatment is just for "maintenance." The actress first revealed her illness in 2011. At that time, her spokesperson said that the actress "made the decision to check in to a mental health facility for a brief stay to treat her Bipolar II disorder."

"After dealing with the stress of the past year, Catherine made the decision to check into a mental health facility for a brief stay to treat her bipolar II disorder," her publicist said about the condition of the actress. "She's feeling great and looking forward to starting work this week on two upcoming films."

Jones reportedly was under a lot of stress since her husband battled stage four throat cancer in 2010.

"It's been the most difficult year of her life," a family source said. "She's been through hell! The pressure has been almost unbearable."

"Catherine had a lot of trouble coping. She was chain-smoking and drinking. It was tearing Catherine apart to see such a vital man as Michael in such a weakened state. I think she was crumbling," the source said.
