Mother's Day Shocker: NeNe Leakes Reveals Reason Behind Her Reunion Meltdown –– 'My Mother Abandoned Me'

Leakes explained, "I never want to be a victim. I'm a strong woman. My mother didn't raise me. My father never claimed me. I have been lied to; I have been cheated on; I have been in abusive relationship, but everybody else got to be like, 'I've been bullied, my mom was never there for me, my brother died.'

"Everybody else had all these issues that caused them to feel this way whenever I was in the room, but I was never that person who had any kind of issue myself. I never had anything. I did not like that."

As the others shouted back and forth, Leakes suddenly began to cry and shake.

"We need to listen to what NeNe has to say right now," Dr. Jeff said, but Leakes whispered, "I don't have anything to say."

Cynthia Bailey told Leakes she was proud of her because she had achieved so much without having a mother's support, while Kenya Moore (who also was estranged from her mom) said they had a lot in common.

But none of this helped as Leakes kept sobbing, then stood up and said, "I can't talk about my mom!" while clinging to Dr. Jeff.

Williams, Bailey, and Parks walked off the set with Leakes, where her husband Gregg Leakes gave her a hug.

While Leakes recovered her composure in the bathroom, Gregg told Cohen that Leakes' mom had five children when she was very young and couldn't raise them all, so NeNe was sent to Athens, Georgia, to be raised by her aunt.

"She has always wondered why she had to be one of the ones sent away -- it's bugged her all her life," Gregg told Cohen.

Leakes eventually returned to the set and told Cohen, "I'm good."

But her leg shook uncontrollably as she said, "Maybe I have been misunderstood somewhere along the line … people think I haven't been through anything in my life. It's just really hard to talk about my mom."

Cohen asked Bailey about frenemy Leakes and she said "What I saw was my ex-friend having a real moment -- NeNe is a survivor."

Moore said she was showing strength by finally showing her vulnerability.

In the end, Leakes felt the reunion was healing and that she and the other Atlanta gals "share a sisterhood."

Earlier, however, tempers had flared when Bailey's husband Peter Thomas suggested everyone owed Moore an apology over the Apollo Nida issue.

Also, Thomas had been accused of cheating on Bailey -- but joked that if he cheated, it wouldn't be with a barmaid but with someone like J. Lo or Beyonce!

Cohen asked a very cleavage-heavy Burruss if she'd had a boob job, but the Kandi Factory owner denied it, laughing, "I've gotten fatter, period in the past couple of years," and saying she'd also gotten puffy while taking hormones in an attempt to get pregnant. (She and Tucker are still working on it.)

Leakes and Bailey also relived the end of their friendship, and the model was particularly mad Leakes had said she was expendable, with her infamous "Girl, bye!" comment.

Bailey accused Leakes of trying "to take food off of my table."

After a tense showdown, Leakes said, "I wish her well. That's it."

Viewers also learned about Leakes' health, which had prevented her from going on the housewives' trip to the Philippines this season: "I take a pill every day to thin my blood."

Season seven of RHOA ended with a group hug -- but fans won't have to wait long for more fussing and fighting, as Burruss and Tucker's new Bravo spinoff, Kandi's Ski Trip, begins airing next Sunday.
