A teenager killed herself after becoming obsessed about achieving the “perfect” figure and taking thousands of pictures and videos of her own body captioned with negative comments.

Hannah Carpenter, 18, who had struggled with eating disorders, was found dead in woods near her home in Redruth, Cornwall, her inquest was told.

Following the hearing in Truro on Tuesday, her father, David Carpenter, said he felt that she had been striving for the sort of figure celebrated in magazines and on the internet.

He said: “It is all about the body image now and striving for something that is not possible. The pressure of it all became too much for her.”

Carpenter said his daughter had an eating disorder from the age of 13. Her family believed she had recovered but images found on her phone after her death revealed she was still very concerned at her weight.

He said: “There were thousands of pictures of her looking at herself. She was videoing her legs from all different actions and it was all: ‘Do I look fat in this? Do I look fat in that?’ She was taking pictures every single day.

“Even though she looked stunning she thought she was fat, worthless and talentless. She was not – she was fantastic at everything but what you see in the mirror is sometimes not want you look like.

“She could not see this beautiful young woman that we could. She would see a picture of herself but not be able to associate herself with it.”

He added: “She had a loving boyfriend and a good job. She had loving parents and had everything anybody would want. But it was immaterial to her. For her, it was all about what she looked like.”

Hannah’s boyfriend, Luke Whittaker, who worked with her at the chain TK Maxx, said he last saw her the day before she disappeared. He said: “I honestly don’t know what triggered it. Something was up but she would not tell me.

“She was just naturally brilliant at everything she turned her hand to. But she couldn’t see it. She always used the past tense to me about her eating disorder. We had no idea it had got that bad again.”

The inquest was told that Carpenter’s body was found in woods on 31 May, the day after her family reported her missing to police. Her red Citroën car was found nearby.

Coroner Barrie Van Den Berg ruled that the 18-year-old had killed herself. He said: “This was a case where Hannah was concealing the way she was feeling from virtually everybody.”

Addressing family members, he said: “Parents never expect to lose a child – it is just wrong. Anybody who has heard you heartbreaking story about your beautiful daughter would wish the greatest sympathy to you all.”
