Naomi Louise Bellamy, of Elm Road, Doncaster, died at a flat in Park House on Bernard Road in Sheffield last July.
Naomi had recently lost her long-term partner and she was staying with her friend Rebecca Ogbourne for emotional support.
However, after Rebecca had left for work on the evening of Saturday, July 13, Naomi asphyxiated herself.
She left a note, as well as video messages on Rebecca’s phone, which were not picked up until later that evening.
The note said that her actions had been a ‘long-time coming’ and the videos showed her ‘apologising, explaining things and saying goodbye’.
When Rebecca returned home later that night, she found Naomi unresponsive and tried to perform CPR while waiting for an ambulance.
When paramedics arrived, however, it was clear that she had passed away.
An inquest into her death at Sheffield Coroners’ Court on Monday heard evidence from Naomi’s GP, a mental health professional from Northern General Hospital and her family.
Testimony read to the court from her GP in Doncaster said she had never visited them since registering and had no significant past medical history.
Naomi had, however, visited hospital in Sheffield in the weeks before she died after self-harming with scissors, but self-discharged before she could be assessed.
And after her death, her family told the police her partner’s death had left her ‘inconsolable’ and that they had been ‘extremely worried about her well-being’.
A post-mortem examination found Naomi died of asphyxia in relation to helium inhalation.
Both alcohol and paracetamol were also found in her system, but neither in significant amounts.
In ruling Naomi’s death a suicide, assistant coroner Tanyka Rawden said her thoughts were with her family, who were not present in court because of the coronavirus crisis.
She said: “I offer my sincere condolences to all who knew her. She was clearly someone who was well thought of.”
“I can’t imagine what her family and friends are going through. It is an absolute tragedy.”
