Gia Allemand's mother Donna Micheletti feels her daughter's menstrual cycle, and not depression, pushed her over the edge and into committing suicide on August 12.

"She was not depressed. Sometimes when it was that time of the month, [she'd] get insecure and go to a dark spot, and she'd feel like nobody cared, and she would just snowball," Micheletti said during a Tuesday appearance on Dr. Phil.

"And I would tell her, 'Come on, this is not real. This person does love you. It's not this.' And she'd look for excuses and people to find fault and push them away because she just got so fearful because she was always afraid of abandonment."

"And she would do that on a regular basis?" Dr. Phil star Phil McGraw asked.

"No, once in awhile -- not all the time," Micheletti replied.

"Was it always timed to that time of the month?" Dr. Phil questioned for clarification.

"Not bad like this one," Micheletti said, explaining how Allemand had about a 30-minute phone conversation with her prior to the suicide attempt in which the former The Bachelor and Bachelor Pad contestant opened up about how she was unhappy and felt alone and unloved.

"Not bad like that, maybe three times in her life, really bad," Micheletti noted. "But this blew me away. I did not expect this. I figured I could talk to her like I always do and I could maybe make he understand and see."

Micheletti suggested the emotional effects of Allemand's menstrual cycle blurred her daughter's vision.

"That day, with how she felt with her menstrual cycle, she could not see clearly. And I knew that happened to her and I was trying to talk to her. I was trying to be careful with what I say because I didn't want to upset her more and I was nervous," Micheletti said.

"So you were walking a tightrope, huh?" Dr. Phil asked.

"Yes," Micheletti replied.

"But you're saying that this menstrual cycle took such a..." Dr. Phil began.

"An impact..." Micheletti interjected.

"A powerful hold on her that she would turn..." Dr. Phil continued.

"Like night and day. It would come out of nowhere," Micheletti said, explaining how Allemand's boyfriend Ryan Anderson was often a topic of discussion when the former reality TV star would get down on herself.

"All of a sudden, something would click in there and she would say, 'This isn't right. He doesn't love me. He's not this. He's not that' -- because of her insecurities inside herself."

Dr. Phil wondered when Micheletti realized her last conversation with Allemand was heading down a similar road to talks they've had before.

"What was the first thing she said to you that made you know this was one of those times that she was in that dark place?" Dr. Phil asked.

"'I'm not happy. I can't go on with this anymore,'" Micheletti noted. "I said, 'G, you'll be fine. We'll work through this like we always do.'"

However, Micheletti admitted she didn't think Allemand would ever get to the point of feeling the need to take her own life. In fact, the pair's final conversation led Micheletti to believe she was going to see her daughter the following day.

Allemand asked Micheletti to book a ticket to fly to see her in New Orleans because she needed a hug. Micheletti thought she could brighten her daughter's mood in no time. But it wasn't until after Allemand killed herself that Micheletti replayed the conversation in her mind and realized there was a big red flag regarding Allemand's state of mind.

Allemand suggested Micheletti bring a friend along to New Orleans despite the fact the pair would always spend time together alone. In retrospect, Micheletti believes Allemand was hoping her mother would have someone there for her when making the burial arrangements.

While it was clear Allemand had experienced several very low moments in her life, Micheletti made it known she had sought help for her daughter on numerous occasions.

"She'd sometimes have radical changes in her personality. Did she ever see anyone for that? Was she ever diagnosed or treated or medicated?" Dr. Phil asked.

"I've tried. I took her to quite a few places over the years many times. And after one visit, two visits, that's it. She wouldn't go back and she's an adult. I can't do it. I can take you, but I can't force you," Micheletti said.

Official documents obtained by TMZ state Anderson found the former reality TV star last month unconscious, sitting on the steps of a spiral staircase in his home with a vacuum cleaner cord "wrapped around her neck many times."

When Anderson found Allemand, she had reportedly been without oxygen for at least 30 minutes by that point and left a suicide note in which she stated Micheletti would receive all of her property. Anderson then immediately contacted 911 and Allemand was taken to University Hospital in New Orleans. 

After remaining in critical condition and on life support for two days, Allemand passed away when her life support was withdrawn due to the fact she had "a critical loss of brain and organ function," according to a previous statement released by Allemand's representative.
