Amy Duggar has been extremely open about the traumas she faced in her childhood during her time on Marriage Boot Camp.
One of the most horrific stories she's told involves a certain family member grabbing her by the throat and lifting her up to the ceiling.
She's been hesitant to reveal exactly which member of her large family did the terrible deed ... until now.
In this sneak peek for tonight's brand new episode of Marriage Boot Camp, Amy is revealing not only who grabbed her by the throat -- she's also revealing why he did it.
And her story is more heartbreaking than we could have imagined.
According to Amy, her father is the family member who got physical with her.
"My dad was like, 'Amy, did you brush your teeth?'" she recalls. "And I was like, 'Yeah, Daddy'"
"And he was like 'No you didn't.' And he picked me up by the throat, all the way up to the ceiling. He was like 'You will brush your teeth.' And I was scared sh-tless."
Amy revealed that not only did her own father choke her because he thought she lied about brushing her teeth, but that once he even tried to run her over with a car.
