The hearinq at Bolton was told Miss Bradford, who started taking tablets for migraines in her teens, lost her father in a road traffic accident in Blackpool in 2001 and had taken it badly.
Her troubles with Nurofen Plus began after the breakdown of a relationship in 2005 and a fall down the stairs in 2010 which required her to have surgery to repair fractured vertebrae,

Miss Bradford had also spoken of her stress, anxiety and depression and was 'lonely' after working unsociable hours and had drifted apart from friends who had settled down, the hearing heard.
Further to this, after contracting meningitis, she was diagnosed with a fractured skull which was believed to have been caused by her fall.
Toxicology tests showed Miss Bradford had large amounts of cocaine in her system and had also taken amphetamines and ecstasy
Miss Bradford told friends she took Nurofen for pain relief but soon realised she had a problem and told her local chemists not to sell it to her.
But after relapsing she travelled to other chemists to obtain them.
In 2010 Miss Bradford was seen by a mental health crisis team and was prescribed methadone to try and wean her off the ibuprofen based tablets.
Her mother Dianne Westwell, who knew of her daughter’s addiction, told the inquest that on 21 November 2013, she was called by one of her daughter's work colleagues to say she was 'unsteady on her feet and didn't appear herself'.
Miss Westwell said: 'She wasn’t well it was obvious. She looked like she was drunk, she was slurring her words, she wasn’t drunk. She said she hadn’t taken any tablets but from her demeanor it was obvious.'
She added that she found an empty Nurofen Plus 32 pill packet in her daughter’s bag and assumed that her daughter had taken them all. She told the inquest that she took her daughter to a GP who then referred her to the hospital.
Miss Bradford told hospital staff that she hadn’t meant to harm herself but that the tablets helped to ease her pain. She was diagnosed with a kidney problem and told to stop taking ibuprofen before being discharged the following day.
Mrs Westwell said she had last seen her daughter on November 27, 2013, three days before her death on 1 December, and she had appeared 'happy'.
She said she was unaware of her daughter using any other drugs, apart from in her teens.
Mrs Westwell said her daughter had lost friends due to her unsociable working hours and that many of them were married with children which left her feeling 'very lonely'.
On the day of her death Mrs Westwell asked her daughter over for Sunday lunch. After she failed to respond she went to her daughter's house where she found her body inside.
Miss Bradford was so addicted to Nurofen that she asked her local chemists to stop selling them to her
Miss Bradford’s sister Erika told the inquest that before Miss Bradford's death the pair had an argument over text message during which she told her to 'sort herself out'.
Mental health nurse Karen Lee said Miss Bradford had told her that previous treatment to curb her Nurofen addiction hadn’t worked.
She said: 'She stated she had the trauma of losing her father, she suffered from back pain problems and was dealing with stress. She said she had stresses at work. She did continue to work. In her opinion they helped the anxiety. She categorically denied that she was taking illicit drugs.'
GP Dr John Coleman said that Miss Bradford had been prescribed pain relief for her back pain and anti-depressants but that she had not disclosed to him that she had taken illicit drugs.
He said: 'To me she said it was for pain, I think an aspect was to calm her down. She said she had been struggling with her mood, she had low days.'
Pathologist Dr Steven Wells said Miss Bradford had suffered kidney disease as a result of Ibuprofen abuse.
But he said toxicology tests showed that she had not taken Nurofen on the day of her death but that there was fatal levels of cocaine at 11.3mg per litre. She had also taken amphetamines and ecstasy.
Coroner Mr Alan Walsh recorded that her death was as a result of drug misuse but said mystery surrounded her access and misuse of the illicit drugs.
Mr Walsh said Miss Bradford 'clearly had problems arising from events in the past', such as the death of her father, which was compounded by migraines and injures which caused 'pain frequently and regularly'.
He said: 'I accept there is no evidence that she took overdoses of Nurofen to end her life. The fact that is extremely difficult to assess is her use of illicit drugs.
'It’s a mystery to me as to how she obtained the drugs or when she used the drugs. Her family were not aware.
'Nobody could have seen her death arising. I will accept that she was not a regular user of those drugs, I will accept she was a relatively inexperienced user.
'It may well have been she had not realised how this quantity of drugs may have affected her. It’s sad that she felt the need to take these illicit drugs.'
