Emily Atack broke down in tears as she admitted feeling to blame for being bombarded with hundreds of unsolicited messages a day.
The former 'Inbetweeners' actress had a tearful conversation with her mum Kate Robbins about being sent horrific messages on social media, and her former 'dinnerladies' star mother admitted she felt her daughter had been "violated" and she wasn't able to protect her.
Speaking on her documentary 'Emily Atack: Asking For It?', Emily told her mum: "I see the pain in your face when we try and talk about things.
"We can't talk about them because it's too difficult."
'Spitting Image' star Kate replied: "It's very difficult - the overriding feeling of guilt is a difficult one to explain to people."
Emily, 33, then began to cry, and said: "Sorry, I don't know why I'm getting upset I think I'm really tired. Sorry it's just so uncomfortable."
Later in the show, Kate admitted she felt she hadn't protected her daughter.
After reading some of the messages, she said: "I didn't expect it to be so vile. I feel my daughter had been violated and I couldn't protect you."
Also on the BBC documentary, Emily said she has "never been in so much pain" than when she was in her school years and getting more drunk than others at parties and "going off with all the boys".
She added: "What I really want to get out there is that that girl at school, we all know one, the girl who gets more drunk than everyone at a party and she's going off with all the boys, there's another story there.
"She's not doing that because she wants to, because she likes sex and getting her boobs out, she feels that there is no other way to be at the moment and she's looking for something in all the wrong places.
"It's too easy to go 's***' but you shouldn't have to search for those things when you're 13 years old. If you are, there's obviously some pain going on.
"I am speaking from experience, I have never been in so much pain than when I was behaving that way."
