Donna Micheletti's voice choked with tears as she told Dr. Phil McGraw about her daughter Gia Allemand's final moments as she tried to commit suicide on Aug. 12.
In the heartbreaking interview set to air on Dr. Phil on Tuesday, Micheletti revealed she was on the phone with her daughter, 29, as she hanged herself in her New Orleans apartment.
Micheletti believes that the Bachelor star called her because "I'm the closest person in the world to her and she didn't want to be alone when she left this world. So she wanted Mommy to be there, I guess."
"It destroys me but if it made her feel better, then that's fine," she added. "I don't mind dealing with this."
Allemand was found unconscious by her boyfriend, NBA player Ryan Anderson, who performed CPR before she was rushed to the hospital and placed on life support. She died two days later.
A police report revealed that hours before she hanged herself, Allemand had argued with her boyfriend over suspicions he'd been unfaithful.
"I'm really mad that she did this for no reason," Micheletti said. "In 12 hours it would have been fine. I'm really angry."
Dr. Phil also talks to Jake Pavelka, whose season of The Bachelor Allemand appeared on.
"I've never lost anybody close to me," the reality star, 35, admitted with tears in his eyes. "Gia really understood me. We got really close after the show. We had such a special relationship. I can't tell you how lucky I feel that I knew her, but I wish it was not for such a short time, because I've never met anybody like her."
