Miss Horn (19) was seriously injured when she was struck head-on by a truck on Thames Highway in March last year.
Her injuries included a cracked skull, swollen brain, collapsed lung, broken jaw, cracked mouth, broken collarbone, four broken ribs, skin torn from a foot and chipped teeth.
Her family was told she would not live and, if by some miracle she did, she would be either in a vegetative state or paralysed down the left side of her body.
Yesterday, Miss Horn said she wanted to thank everybody who had helped her, from the hospital staff in Dunedin and Oamaru, to emergency services personnel, members of the public who went to her assistance at the accident scene, and her family and friends.
A 22-year-old associate will be sentenced in the Oamaru District Court next Wednesday on a charge of criminal nuisance by throwing herself in front of a truck.
Miss Horn attempted to pull her associate from the truck's path, but her own momentum caused her to fall directly into the path of the truck and she was run over.
She spent five months in Dunedin Hospital and in the ISIS recuperation centre at Wakari Hospital.
A piece of her skull was put in her stomach to keep it alive, while allowing her brain to heal.
When she regained consciousness, she was so heavily medicated she "couldn't get my head together".
It took several weeks to learn to talk again after having had a tracheostomy, and she also had to relearn to walk.
Asked the state of her health yesterday, Miss Horn beamed and said she was "peachy".
However, she had short-term memory loss and headaches and her right leg occasionally twitched.
Miss Horn said she hoped to become a social worker.
"The best people for that job are the ones that have been there.
"I think I'd be quite good at that, eventually."
