Samantha Hooker, nee Stone, accelerated towards her former husband Peter, mounting a pavement and pinning him against the wall of a home at Schofields in Sydney's west on August 8, 2023.
"I understand he got hurt, I just wanted him to leave me alone," she told consultant forensic psychiatrist Andrew Ellis in April.
"I understand I need to be punished."
Mr Hooker suffered serious injuries and died from complications more than three weeks after the incident.
His former-wife was found not guilty of murder in March after a jury heard she had experienced extreme provocation and a significant mental impairment after years of abuse.
She pleaded guilty to the lesser charge of manslaughter and is awaiting sentencing in the NSW Supreme Court.
On the day she ran over her ex-husband, Hooker drove to his home and was physically violent towards him, Justice Hament Dhanji heard in April.
In a report tendered with the court, Dr Ellis wrote that Hooker could not remember her motive for driving at her ex-husband or recollect the immediate events beforehand.
He wrote that the 47-year-old met the criteria for post-traumatic stress disorder.
Drone footage played to the court showed the route she took driving at her ex-husband.
Tyre marks are seen on the pavement while the silver hatchback with Medlab Pathology branding sits with its front end smashed against the side of the brick house.
Further court documents seen by AAP reveal Hooker's mental distress after being charged.
An affidavit by solicitor Michael Large states that she became extremely emotional during her arraignment in August 2025, crying and grabbing his arm as she entered her pleas.
"I observed Ms Stone to walk out of court and collapse a short distance from the court room," he wrote.Â
"I observed her to vomit on the floor."
Paramedics were called to render aid on this occasion and twice more during the trial when she fainted, Mr Large wrote.
Hooker has been supported by a throng of family and friends in court.
In a character reference, Lisa Stone said she knew about the toxicity plaguing the relationship between her 47-year-old elder sister and the woman's husband.
She said she tried to get her to break up years ago.
"It remains a significant regret of mine that I was unable to convince her to leave," she wrote.
"I feel like I failed them."
Her former employer Fiona McLoughlin wrote of Hooker's empathy, compassion and resilience while working as a room attendant at Ronald McDonald House Charities from 2018 to 2020.
"Nanny Sam" had a compassionate nature, buying groceries for parents of sick children out of her own pocket and raising thousands of dollars for the charity by cutting her long hair.
A short one-page victim impact statement by Mr Hooker's mother Tracey Hooker-Dargin said the death of her son had taken a toll on her and the family.
"I wake up from nightmares and can't get back to sleep," she wrote.
"I'm never going to get over this."
