A 'bubbly' 14-year-old girl was so intent on hiding her depression from her family after breaking up with a boyfriend they had no clue she was suffering, an inquest heard today.

The Year 9 pupil was found dead at their five-bedroomed home in Newbury, Berkshire, when her parents and brother returned from a school open evening.

The student left a series of heartbreaking notes, including one to her ex-boyfriend which read: 'I have decided to end my life. I’ve suffered from depression for about three years.

'I guess keeping everything bottled up for three years just kills. I have to end this pain.'

The coroner was told that the girl was found hanged in the garage of the £750,000 home.

The talented writer and artist had broken up with a boyfriend late last year but had not spoken of being unhappy.

Instead the outwardly happy girl had repeatedly talked of the future and even about which university she might like to attend, her devastated father told the inquest.

Her father, a dentist, said his daughter was never put under any pressure by her family and they encouraged her to be happy, enjoying rap music with her friends and spending time reading in her bedroom.

However, when he and his wife returned from the school open evening with their son on June 20 this year they discovered her body.

They immediately tried to resuscitate her as they waited for ambulance crews to arrive.

Paramedics rushed the youngster to the North Hampshire Hospital in Basingstoke where accident and emergency staff spent an hour trying to save her.

As the family went out that evening her mother shouted to her daughter that they were leaving she replied 'I love you mum.'

The father, 62, told the inquest in Newbury that his wife and daughter had a relationship 'like best friends' and said he had 'no idea' his daughter may have been unhappy.

'It’s a complete mystery and has devastated our family,' he said.

His 47-year-old wife did not attend today’s inquest but said in a statement she and her daughter would go shopping and power walking together as well as sharing make-up tips.

'She never showed any signs of depression and was always a happy, bubbly girl.

'She gave no indication she was about to do this.

'We have always been an open family and talked about things and she has been a happy, independent child.”

The Year 9 pupil and her family moved back to England from Cyprus in April 2011.

A friend said that she had been a 'shadow of herself' in the months before she died and had confided in her about feeling unhappy.

Police discovered photographs and pictures on the Year Nine pupil’s iPod of 'emo images' depicting despair with characters crying blood and images of fallen angels.

They also found a series of essays with headings including ‘Trust, ‘Dark secrets’, ‘Time to die’, ‘Your fault’ and ‘I just want you back’.

Recording an open verdict Berkshire coroner Peter Bedford said: 'What is overwhelmingly clear from the evidence is that those who knew the girl best - her family and friends and school teachers - had no expectation, no inkling, even with the benefit of hindsight, no understanding what happened to end her life at such a young age.'

Following her death on June 20 this year, her school headteacher paid tribute to her as a “lovely, talented young person”.
