'You Are A Psycho!' Farrah Explodes At Mom Debra In Shocking 'Boot Camp' Brawl

Farrah Abraham's badly damaged relationship with her mom, Debra, is WAY beyond repair!

In an exclusive sneak-peek of Marriage Boot Camp: Reality Stars Family Edition obtained by RadarOnline.com, the 25-year-old Teen Mom star and father, Michael, rip into Debra when Debra returns to the house after leaving to go spend time with her boyfriend!

As previously reported, Debra – who has been separated from Michael since Farrrah first rose to fame – told her daughter in a previous episode that she would be ditching for a short time during filming. At the time, Farrah had speculated that her mother was getting engaged.

In the shocking preview showing Debra's return, Farrah asks her mom, "What was this life or death situation? Did you get engaged?"

After Debra tells her daughter (in front of all other cast mates) that she did NOT get engaged, all hell breaks loose on set!

"You don't want to be here with me," Farrah screams before dad Michael joins in on the attack of his ex-wife, telling her, "I am not your f****g mat no more!"

Deflecting the blame, Debra tells producers, "Farrah has a fear of abandonment. She is afraid to see me with the love of my life," before Farrah rips into her mom with the worst insult ever !

"You are a psycho stupid twisted manipulative mother f*****g! You are not my f*****g mom. You are a f*****g stranger off the f*****g street as far as I'm concerned. You are a stupid dumb b****!," the controversial reality star screams.
