The paper reported that she made a failed suicide attempt on January 6, and police found her body in her Manchester flat on Saturday, January 11, after the alarm was raised by her mother in Auckland.
An inquest in Bolton was read a statement from her mother, Priscilla Cameron, the Daily Mail reported.
Mrs Cameron said her daughter, who had a history of depression, had wanted to return home after struggling with work and the death of her grandfather.
"She was passionate about science. When she got the job in England she was so anxious about moving from a small city to a large city on the other side of the world," Mrs Cameron said.
"But she was very outgoing and friendly and expecting to make new friends. She managed her depression by always having a hobby outside of study."
Dr Maxwell-Cameron, who graduated from the University of Otago in 2010 with a first-class chemistry bachelor of science degree, enjoyed karate, rowing, acrobatics and fire dancing.
Her mother told the inquest her daughter had been alone at Christmas, and she seemed a bit low.
On January 6, Isobel phoned her mother to say she had tried to take her own life.
"She said she was feeling the worst she had ever felt," her mother told the inquest.
After speaking to her mother, Isobel saw a psychiatrist and was prescribed anti-depressants.
Mrs Cameron tried calling and texting her daughter and when she got no reply, she phoned local police.
"I regret not encouraging her to come home and not calling her on Saturday night," the Mail reported Mrs Cameron as telling the inquest.
Manchester West Coroner Alan Walsh said he found Dr Maxwell-Cameron's death "to be an enormous tragedy".
"A young, talented, intelligent, vibrant young lady who came to England from New Zealand believing she was going to further her education by contributing in terms of research to projects that might benefit others," he said. "It is a tragedy of utmost proportion."
Otago University's Professor David Larsen, who supervised Dr Maxwell-Cameron's PhD work on the chemical synthesis of molecules, was devastated by the news.
"We were all shocked and deeply saddened by the events earlier this year and it has affected a lot of people," he said.
