Her right foot, she said, now "sort of flops" because of the nerve damage.
It meant she could not attend training courses in Christchurch and all but ended her dreams of a career in agriculture.
The victim told the court she struggled to stand for long periods and could not walk any great distance.
On December 21 she was socialising with a group of people including Bachop.
A disagreement between the pair turned physical; Bachop grabbed the woman's hair and she responded by punching the defendant in the face.
The victim went to lie down on a bed, but it was not over.
Bachop went to a communal kitchen and armed herself with a plastic-handled 30cm kitchen knife "similar in shape to a filleting knife", police said.
She burst into the room where the victim was lying and yelled "I'm going to stab you".
And she did.
As the woman tried to use her legs to repel the attack, Bachop stabbed her three times — once in each knee and once in the back, narrowly missing the victim's lung.
She told the court she was unable to move her legs for seven weeks and had to be sponge-washed by family.
Defence counsel Anne Stevens QC said Bachop was an intravenous drug user and had no stable address at the time of the incident.
She had requested help with her issues last year and continued to seek assistance.
Her goal, the court heard, was to attend a kaupapa Maori residential programme in Christchurch as soon as she could.
Judge Michael Crosbie said Bachop's life had been "a series of tragedies from the get go" and it would take a long and concerted effort to change its course.
The court heard the defendant had more than 100 convictions to her name and had repeatedly breached court orders.
Prison was the only available outcome, the judge said.
