text: A teenage farmer who struggled with anorexia died after she took an overdose of an animal medication. Charlotte Cobbald, 17, took the deadly medicine, which her father Stephen was keeping illegally, and injected it after saying she felt like a 'failure'. She then ran away from her father, saying 'let me die', before she collapsed in a field and her family called 999, an inquest heard. Paramedics fought to save her and took her in an ambulance to hospital, but Charlotte died from the effects of the drug. Overdose: 17-year-old farmer Charlotte Cobbald died while suffering from anorexia and depression . At the time she died in August, Charlotte was visiting the family farm in Acton, Suffolk while on day release from a mental health unit where she was treated for anorexia and depression. She was an A* GCSE student who had a talent for sheep farming, but was a 'perfectionist' who had battled anorexia and depression, the hearing was told. On August 4 she came home and took some training sheepdogs out with her father, then told him she felt she was a 'complete failure'. They returned to the farm office where farm secretary Katherine Turner was working. While her father stood at the door, Charlotte went over to a fridge full of veterinary medication, found the antibiotics - used to treat farm animals - and injected herself with the drug. Mrs Turner said: 'I knew she was unwell but she didn't seem too bad, there was no immediate cause or concern. 'I don't know how we didn't see. Mr Cobbald seemed to know something had happened. He said, "Have you done something?" and she replied yes. 'She just ran. I got in another vehicle and followed them. She was saying, "Leave me alone, let me die, leave me to die." 'She slumped and she was carried into the back of the car. In the office he sat on a chair holding her and he said she'd stopped breathing.' 'Perfectionist': An inquest heard that Charlotte suffered from a desire to be the best at all times . When paramedics arrived, they had to ask their colleagues to Google the medicine because they had no idea of its effects. David Hall, inspector at the Veterinary Medical Directorate, visited the farm after Charlotte's death and said her father admitted buying the antibiotic from a lorry driver, but had forgotten that he still had some left. He did not enter the drug into his farm's medicine book, which is a legal requirement. Dr Sukhi Khaira of the North Essex Partnership University NHS Trust told the inquest that Charlotte should not have been allowed to visit the farm without a formal risk assessment. She had lost around 20kg in 2013, and went through a period of not talking to her father. She also had a history of self-harming. Clinical psychologist Dr Kevin Beardsworth said she was a 'perfectionist', adding: 'There was a significant sense of hopelessness and helplessness. She had exceptionally high standards for herself, she did not feel good enough. 'If she got 99 out of 100 she would be unhappy, she was a perfectionist and this is seen in anorexia. She was bullied at school and began to isolate herself because she was focussed on her work.' Coroner Yvonne Blake recorded a narrative verdict, saying she could not be sure that Charlotte meant to kill herself and suggesting that her actions were a cry for help. 'Charlotte battled with mental health illnesses including anorexia,' she said. 'She was hospitalised and started to improve so she was allowed on home leave to her father's farm. 'From what I've read from Charlotte's state of mind and from the professionals caring for her, she did have problems with self-harm and impulsive acts. 'She told someone straight away which suggests she wanted help for what she'd done.' After the hearing, Charlotte's mother Hilary said: 'Before she became unwell she had an inner zest for life and excitedly made dreams and plans for her future. 'Her beautiful smile and cheeky laughter was like the sunshine in summer, never far away and readily present. 'The acute trauma she tried to battle, despite the therapy received, supported by ourselves and her friends, took away her sunshine and she lost her battle to live.'
