A woman with a two-year-old daughter hanged herself while suffering from depression, an inquest heard.
Rochane Smith’s fiancé, William Lockley, became concerned after she locked herself in the bathroom of the home they shared with his parents.
He broke the door down and made a desperate bid to save her life.
The inquest heard that Mr Lockley and Miss Smith met in London in 2005 and later moved to Australia, where Jasmine was born in 2012.
PC David Caffyn, who investigated her death, said she had subsequently been admitted to a psychiatric hospital.
She was discharged after three weeks but became deeply depressed later that year, and was not allowed to be alone with her daughter.
She and her fiancé returned to England and Miss Smith, 38, landed a job at a London university.
But PC Caffyn said she began to suffer from lack of self-confidence and feared her relationship with Jasmine was “not going well”.
Miss Smith, of Everton Road, Hordle, was found dead at the family home on March 9.
Mr Lockley and his mother Susan became concerned after she locked herself in the bathroom and failed to answer when they called her name.
PC Caffyn said Mr Lockley forced the bathroom door and found Miss Smith hanged.
He added: “There was no note and the family had not noticed any change in her behaviour that suggested she was feeling that low.”
But Gordon Denson, deputy coroner for Southampton, said: “I’m entirely satisfied from the manner in which took her own life that she intended to do so and it was not merely a cry for help.”
Mr Denson recorded a verdict of suicide.
