The former nurse, who was married to the King of Pop for three years until 1999 and is the mother of his two eldest children, Prince Michael, 17, and Paris, 15, testified in the Jackson family's wrongful death lawsuit against concert promoters AEG Live, that Paris attempted suicide because of Michael's death in 2009.
Speaking in court in Los Angeles on Thursday (15.08.13), she said: ''Their father is dead...I almost lost my daughter.
''She is devastated, she tried to kill herself. She doesn't feel she has a life anymore.''
Debbie gave up custody of the children completely when she and Michael split and said she had no regrets about leaving them with him.
She added: ''Michael wanted to be a father. I didn't sign on to be a mom. I loved him very much and I still do. I wanted him to be a father, I wanted him to have everything that he didn't have growing up, wanted him to experience it with his own child, his own children.''
The Jackson family are suing AEG Live, as they believe the company negligently hired and supervised Dr. Conrad Murray, who is currently serving four years imprisonment for involuntary manslaughter as he administered the lethal dose of Propofol, which killed Michael in 2009.
During her testimony the previous day, Debbie claimed her former employer, Dr. Arnie Klein, and Dr. Steven Hoefflin, held a ''p***ing match'' to see who could supply the 'Thriller' hitmaker with ''better'' drugs.
She said: ''Michael had a very low pain tolerance and his fear of pain was incredible. I think the doctors took advantage of him that way.''
Michael allegedly trusted them to prescribe him with medication but they did not act in his best interest as they consistently tried to outdo each other by giving him stronger doses of painkillers, such as Diprivan and Demerol.
She said: ''These idiots were going back and forth the whole time, not caring about him,'' adding that Dr. Conrad Murray then ''got in there and killed him''.
She said: ''The only physician who ever did anything, the only physician who cared for Michael was Allan Metzger.
''I was probably one of the only ones who said no to MJ.''
