Amy Ratnett was found slumped on the floor of a friend’s house in Blenheim Road, Caversham, on the morning of January 18 after passing out following a heavy night of drinking.

The 29-year-old, who had a long history of overdoses and suicide attempts, had recently turned a corner and just a month before appeared in Cosmopolitan Magazine talking about her battle.

Emotional mum Diane told an inquest at Reading’s Civic Centre on Tuesday: “She always thought of everybody else rather than herself - she wouldn’t do anything to hurt her friends.

“Amy drunk for a long time and then she stopped drinking because she knew mixing it with her medication wasn’t doing her any good. But the last eight months she started drinking again.”

A coroner heard how Amy travelled to Reading by train from her home in Trowbridge, Wiltshire, on January 17 to visit her friend Fay Trezise, who she had met in hospital in 2011.

The pair went into the town centre and had a meal and four cocktails before buying a litre of vodka and heading back to Fay’s house.

They had intended to visit a nearby pub, but Amy got too drunk so Fay left her to sleep slumped up against the end of her bed.

She tried to wake her at 10.20am the next morning, and noticed her skin was “cold to the touch” after getting no response.

Paramedics pronounced her dead at the scene. A post-mortem revealed Amy’s blood alcohol level was two-and-a-half times the drink drive limit and concluded that this, combined with a cocktail of drugs she had taken to combat depression, schizophrenia and insomnia, had a “toxic effect” which caused her body to shut down.

Her dad Paul said: “She was quite happy at the time, there was no reason to expect it. We’re in no doubt there was no intention to harm herself that night.”

Recording a verdict of death by misadventure, Berkshire Coroner Peter Bedford said: “I can’t get past, whatever Amy wished to do, would she ever have done it at Fay’s house knowing how delicate Fay was? I don’t believe that and that raises enough doubt for me that I can’t say beyond all reasonable doubt that she deliberately intended to take her own life.”
