Kathleen Worrall repeatedly stabbed her younger sister and then told a friend, "I am glad the bitch is dead".
During the frenzied attack, her 18-year-old sister Susan had cried: "No Kathleen, I love you, I love you, please stop."
But Worrall believed she did not mean it and was feigning her last gasps.
So she stabbed her only sibling again, yelling: "You're faking it, stop faking it."
Worrall, jailed on Friday for at least four years and three months for manslaughter, has told a psychiatrist she now realises how bizarre her thinking and behaviour had become.
In sentencing the 22-year-old in the NSW Supreme Court, Justice Elizabeth Fullerton accepted that Worrall essentially loved her sister and was deeply remorseful.
The former Australian Catholic University student pleaded guilty to the manslaughter of Susan Worrall, who sustained more than 50 stab wounds, at the family home in Strathfield, in Sydney's west, on October 10, 2008.
The Crown accepted the plea on the basis she was suffering from "an abnormality of the mind" - a mood disorder associated with her non-compliance with her medication regime.
The treatment of her congenital disorder included high doses of corticosteroids, which led to substantial weight gain.
Worrall told a psychiatrist that as a 20-year-old she "looked like a Gladiator", while her father said her weight had made her "an obvious target for attack by her sister".
High levels of testosterone was just one outcome of her medication non-compliance.
Justice Fullerton said that in the week before the stabbing, the sisters came to blows during an argument about a hair straightener.
Days before the attack, Worrall texted a friend saying she was going to kill her sister that night unless persuaded otherwise.
She added that "desperate times call for desperate measures".
On October 10, Worrall armed herself with a knife she had bought from Kmart and two others from the kitchen.
Justice Fullerton said Worrall researched the internet for information on knife wounds, deciding she should sever the carotid artery as she wanted her sister's death to be quick.
"She said that she did not want to hurt her, she just wanted her to disappear," the judge said.
Worrall also said she took three knives "because I knew it would get slippery and I needed backups ... it had to be all or nothing".
She told psychiatrists she thought of killing her sister as she then believed Susan persistently dominated their parents and was "bad for the family".
She changed her mind twice, but after discovering Susan had changed the password on their computer stabbed her as she came out of the bathroom.
"She turned the family against me ... turning off the internet was the last straw," Worrall said.
Justice Fullerton noted Worrall's mother's description of Kathleen as a "gentle, loving, considerate and caring person".
At times she had been bullied at school, but became junior school captain and senior prefect.
"In this case, because of the relationship between the offender and the deceased, their parents suffer a compound loss and a compound tragedy," the judge said.
She concluded the horrific death would never have occurred but for the "complexities associated with Worrall's genetic condition and her interference with her treatment".
She set a maximum jail term of six years.
