Collin Gosselin reflected on the alleged abuse he suffered at the hands of his mother, Kate Gosselin.
Collin, 22, claimed in an interview with ABC that his mom allegedly made him sleep in a locked room in the basement as a way to isolate him from his father, Jon Gosselin.
He claimed that one of his teachers noticed he had a swollen earlobe, which Collin said happened after Kate allegedly "dragged" him across the room by his ear during one abusive incident.

"My teacher saw ... and then I talked to my guidance counselor, and I told them about it," Collin said. "And my mom was not very happy that I spoke about that."
He was eventually pulled from school in the fourth grade, and recalled being "too afraid to say anything" when child protective services questioned abuse allegations.

Gosselin admitted he wasn't sure about life before the cameras arrived at his home to film his family, and told the outlet, "Simply put, my whole life that I lived was a lie."
After one attempt to runaway, Collin claimed his mother allegedly zip-tied him and locked him in his basement room.

"She had put my wrists together ... and my ankles, and took black zip ties and zip-tied my hands and feet together," he alleged to the outlet.
Days before his 12th birthday, Collin claimed Kate had him removed from their home and placed him in an institution. He alleged he was then "pumped with medication" and received little contact from his family.
"I was told, 'This is for your own good,'" he recalled before admitting, "I threatened my mom's income, I threatened her image and people will do anything to protect their reputation, especially my mom."
Kate claimed through the years that Collin suffered from a number of behavioral challenges. Collin wrote that she claimed he had autism, bipolar and obsessive compulsive disorder, but an independent psychological evaluation allegedly showed he didn't have any of those diagnoses.

"Everybody was like, 'Were you surprised when you got this?' I was like, 'No,'" he said. "Because I knew that, it's just that I needed it on paper."
In a sit-down with Jay Shetty ahead of the release of his memoir, "In The Shadow of Eight: Surviving the Reality of My Childhood,' Collin claimed his earliest memories were when camera crews took over his house.
"We were rolling every day, I mean at least a majority of the week, every week of the month of the year," he said.
"And they were always there. There was always lights set up and cameras. And then once it got big enough and it was, it became, it went from ... you know, the big family in the small humble house to the big house."

Gosselin recalled the first indication that life "wasn't normal for a child" when his parents went through a divorce.
"It was never normal," Gosselin noted. "That should never be a thing where you exploit children, where you film them potty training. But when I first had that recollection that ... realization, it was when my parents divorced and I kind of overheard some conversations where my father didn't want that for his children."

"They would do things like they'd have photo shoots where they'd bring in like puppies and they'd be like, 'Kids, play with the puppies, have fun, pet them.' Once they got all the pictures, we'd still want to play with the puppies ... and they'd take the puppies away."
Fox News Digital has reached out to Kate's reps for comment.
While Kate has remained quiet about the allegations, she defended herself over the summer on social media.
The former reality TV star responded to comments on her TikTok posts referencing a few of Collin's claims where he alleged she "forced" him and his seven siblings apart and "pitted them against each other" as they were growing up.
"If you are 100% certain that the accusations against you are lies, my suggestion would be to take him to court and sue him for defamation!" one fan asked. She responded, ""I can’t bc I’m a public figure. Rules are different unfortunately. Or I def would!"
She wrote on another post, "Malice is one of the hardest things to prove. I tried :(. The rules are different for ppl in the public eye."
Gosselin also shared that she "consulted a high power LA attorney" in the past "when other ppl were putting crazy stuff out there," and that is what they told her. "The courts don’t honor it if you’re in the public eye :(" she added.
She later responded to another comment, saying, "Sadly, Only parents who have a mentally ill child understand! It’s so tough and I’m learning that ppl have NO ability to understand unless they’ve been through it themselves."
