'Coronation Street' star Bev Callard attempted to kill herself while severely depressed.
The 52-year-old star - who plays upbeat blonde Liz McDonald in the soap - admits the condition was so bad she cut her wrists and attempted a drug overdose, and eventually had to be treated with electric shock therapy.
She said: "It sounds like something from a Frankenstein movie but electric shock treatment was the last resort to find a cure for the depression paralysing me.
"It was spring 2009 and I'd spent weeks just curled up on my bed in darkness at the Priory clinic in Altrincham, almost comatose and barely able to speak. I remember virtually nothing about this.
"I was in a deep, dark hole and my doctor said I was one of the most extreme cases he'd ever had to treat."
However, the treatment began to work and she managed to return to the 'Coronation Street' cobbles in June 2009.
She added to the News of the World: "I was still on very heavy dosages of drugs and for a couple of hours after taking them I'd slur my words so it sounded as if I were drunk. I had to allow enough time before work to start sounding normal.
"I'm still not 100% better but slowly moving along the road to recovery."
