Shim Eun-ha, who was a popular actress in the 1990s and is married to Bareun Party lawmaker Ji Sang-wook, was rushed to the emergency room Tuesday after apparently overdosing on sleeping pills.
Shim (45) lost consciousness but is in stable condition.
In a text message from Ji's mobile phone on Wednesday, Shim said, "I discovered I had been suffering from post-traumatic stress disorder for some time and recently began taking medication".
"I needed to be treated with drugs, but I overcame my mental problems while raising my children. I am OK now and will soon be heading home".
