A Hull grandma died suddenly in bed after years battling leukaemia and "extreme" chronic pain.
Nicola Patterson passed away aged 47 on January 7 at her home in Dorchester Road, Bransholme.
At the inquest into her death at Hull Coroner's Court, assistant coroner Michael Mellun said it had been a "sad, untimely death", but also "the most peaceful passing that there could be".
Mrs Patterson was born in Beverley and was married on August 31 last year in what was a "very happy day" for the family, the inquest heard.
She also had two daughters and six grandchildren.
The inquest also heard that Mrs Patterson had suffered from "a number of severe health problems", including issues with her joints and long-standing back pain caused by nerve entrapments which Mr Mellun said were "extremely painful" for her.
She also had mental health issues, including depression and anxiety, and a history of drug and alcohol abuse.
She was referred to the adult mental health services in August last year following an overdose, but Mr Mellun made clear at the inquest that the incident had not been an attempt to take her own life.
There had also been an incident last year in which she had entered the North Sea at Whitby while under the influence of alcohol, but again the inquest heard she had not been intending to take her life.

In the early hours of January 7 this year, Mrs Patterson passed away in her sleep from heart failure.
Mr Mellun said that an abnormal heartbeat was a known side effect of a prescribed antidepressant medication which she had been taking at the time of her death - but not at levels above the recommended dosage.
He added that there was "no evidence whatsoever" of foul play, of any suicidal thoughts, of an overdose of prescribed medication or of the use of any illicit drugs or alcohol at the time of her death.

He added: "I do hope that while [her husband], [Mrs Patterson's] daughters and her grandchildren remember that this was a sad, untimely death, it was the most peaceful passing that there could be and I offer my condolences to them."
