A British woman has described her anguish at not being home when her dying daughter made a desperate phone call for help.
Tara Purchase only discovered her daughter's phone call when she returned home and listed to messages on the answerphone.
Ms Purchase said: "I will never be able to forgive myself for not being there for her when she needed me."
Evelyn Purchase, 20, tried to call her mother as she lay dying following medical treatment a coroner described by a British coroner as "substandard", the MailOnline reports.
Ms Purchase discovered her daughter's body in her bedroom after going to check on her.
Miss Purchase was still holding the phone.
An inquest was told that Mahmud Ahmed, a doctor who saw Miss Purchase at a local clinic, failed to check her recent medical history.
Dr Ahmed also conceded he prescribed antidepressants without a proper mental health examination and failed to carry out a full lung examination, the MailOnline reports.
Miss Purchase died of extensive bilateral lung pneumonia with pulmonary abscesses, less than 36 hours after leaving the clinic.
Ms Purchsae said: "I realised that Evelyn had tried to call me and I could hear her dying in the message."
Miss Purchase was prescribed antibiotics despite two other rounds of treatment failing.
Black Country coroner Robin Balmain found Dr Ahmed incorrectly diagnosed Miss Purchase with a chest infection and wrongly assumed she had depressions.
Dr Ahmed also failed to order X-rays at a nearby clinic, despite Ms Purchase saying it was an urgent case.
He said Miss Purchase had not appeared to be distressed about her illness.
Mr Balmain said: "Death was due to a natural cause. A medical examination that took place late on the evening of April 4 was less than optimal."
Mrs Purchase told the MailOnline that her daughter had been ill for several months with a range of symptoms but had been badly let down by doctors.
