Five years ago, she left school after her relationship with her junior college teacher soured.
In April this year, he sent back all her gifts from that time and she took a huge emotional blow.
The 22-year-old woman locked herself in her bedroom and threw all her belongings out of the window, alarming neighbours.
She even sat on the window ledge of her second-storey HDB flat.
The incident occurred at Block 953, Jurong West Street 91, on Monday at about 6.20pm.
The woman's mother, who only identified herself as Madam Lu, told Chinese evening daily Lianhe Wanbao that her daughter locked herself in her room around 5pm.
The woman then started to throw things out of her window, including her dolls and even her mattress, before sitting on the window ledge.
A resident who lives in the same block and wanted to be known only as Mrs Tan, told The New Paper: "At first, she was simply shouting, then suddenly her mattress, her dolls and many other belongings were thrown out of the window.
"It caused such a commotion that people from opposite the road even stopped and watched."
The police and the Singapore Civil Defence Force were called. But it was about an hour later before she finally unlocked the door and was arrested by the police, Wanbao reported.
According to Madam Lu, it all started five years ago when her daughter developed bipolar disorder after breaking up with her junior college teacher.
Said Madam Lu: "She was worried how her friends would look at her, so she refused to be admitted into the Institute of Mental Health for treatment." But she received therapy, and had to juggle her medication and studies.
To take care of her daughter, Madam Lu said she quit her job as a primary school teacher.
But things got worse in April, when her daughter's ex-teacher returned all the gifts she had given him when they were dating.
Madam Lu told Wanbao: "Her sister happened to be overseas and she wasn't that close to her grandparents, so she had nobody to confide in and her emotions took a huge hit."
Her daughter ran away from home two days before Monday's incident, but was found and brought back home, she said.
Police have classified the case as attempted suicide and rash act. Investigations are ongoing.
