An audio tape of a man, reported to be Heather Locklear‘s psychiatrist, requesting emergency assistance at the actress’ house has been publicly released. “I have a patient and I have a feeling she’s suicidal. And I would want someone to go [check on her],” says the caller whose name was apparently redacted before the tape was released to the public.

The 911 call came in on Saturday, March 8. Authorities said they found no problems when they responded to the call and Locklear’s rep said the actress was “fine.”

But The ENQUIRER can exclusively reveal that Locklear has had a years-long battle with booze, drugs and depression, she has detoxed in private, lived with sober companions and secretly been hospitalized for her problems, according to a source.

“Heather was on the phone with her psychiatrist when he became alarmed because she was upset and seemed intoxicated,” a close pal told The ENQUIRER. “At one point Heather said: ‘I’m just so sad and bummed out, I feel like killing myself right now!’

“Her doctor did not take it as an idle threat.”
