Catherine Zeta-Jones sought treatment for mental illness at a Connecticut hospital earlier this month, a rep for the actress have confirmed to PEOPLE.

“After dealing with the stress of the past year, Catherine made the decision to check in to a mental health facility for a brief stay to treat her Bipolar II Disorder,” the rep said in a statement. “She’s feeling great and looking forward to starting work this week on her two upcoming films.”

According to ICYDK, that facility she chose was Silver Hill Hospital near New Canaan, Connecticut. The star reportedly checked in on April 6 and stayed a total of five days.

“There’s no question it’s been a stressful year,” a friend reportedly told PEOPLE. “Catherine has had deal with Michael’s illness and that’s been hard. She went in for a few days because she’s about to start working, and wanted to make sure she’s in top form, which she is.”
