Emily Atack tried to commit suicide at the age of 15.
The 29-year-old actress - who played Charlotte Hinchcliffe on 'The Inbetweeners' - has revealed she downed vodka and then self-harmed after being dumped by a boyfriend during her teens.
Emily told the Sunday People newspaper that she felt "out of control" of her own life.
The actress cut her wrists after splitting from a boyfriend, who'd previously called her a "psycho".
Emily recalled: "I would do drastic things in order to make him get back with me.
"I drank a bottle of vodka and cut my wrists - a cry for help, a cry for attention. I was spiralling. I was too young to cope with my breaking heart and cloudy drunk head."
Emily's mother, actress Kate Robbins, was shocked by her daughter's injuries.
But the actress struggled to speak candidly about her personal troubles.
She said: "My mum would beg me to open up and speak to her but I just couldn't.
"She started to see cuts on my arms and it broke her heart. I'll never forgive myself for harming my body in that way, and to this day I still have no idea why I did that.
"I didn't want to die. I just felt so out of control of everything and it was almost like a 'f**k you to everyone, cos I can do this if I want!' sort of thing. A rebellion, I guess. I saw it like I had no other choice."
