A woman with manic depression who died after taking a massive overdose may not have been taking her medication, an inquest heard.
Aliye Seif Al-Said was found collapsed in her bedroom along with four empty packets of prescription medication Epilim.
Worried sister Hudham found her after checking on the 45-year-old when she failed to turn up for an evening meal at her home.
She dialled 999 after failing to wake her and spotting vomit on the bed and floor.
Ms Seif Al-Said, an administration supervisor, was rushed to Queen Alexandra Hospital, Cosham, but attempts by medics to rescuscitate her were futile.
She was pronounced dead at 9.21pm on May 5 last year.
Tests later revealed 190mg of Epilim per litre of blood in her system – well over the therapeutic dosage of 40 to 100mg/l.
A Portsmouth inquest heard Zanzibar-born Ms Seif Al-Said, of Brougham Road, Southsea, had suffered from depression for seven years.
She suffered from bipolar syndrome, also known as manic depression, and had admitted to her sister that she did not always take her medication.
But her sister did not believe her sister took her own life. She told the inquest: 'She never talked about harming herself, even when she was in hospital and all of the other patients said they were wanting to commit suicide and they were unhappy.'
David Horsley, coroner for Portsmouth and south-east Hampshire, recorded a verdict that Ms Seif Al-Said took her own life while suffering from a serious psychiatric illness.
