The Bachelor star Gia Allemand, who took her own life last month, often suffered major mood swings that her mother believes were caused by one major factor:
Her menstrual cycle.
A grieving Donna Micheletti told Dr. Phil Tuesday that daughter Gia's intense PMS clouded her thinking and likely contributed to her suicide attempt.
"She was not depressed. Sometimes, when it was that time of the month, she would get insecure and go to a dark spot, and feel like nobody cared," Micheletti said.
"She just snowballed."
Donna, who lives in New York, she spoke to her in New Orleans the night of Gia Allemand's suicide attempt and booked her a flight to visit the next day.
