Snatched off a Vienna street in 1998 when she was 10 years old Natasha Kampusch described how she only dreamt of escaping and had also thought about beheading her captor, Wolfgang Priklopil, with an axe.
"I always had the thought: Surely I didn't come into the world so I could be locked up and my life completely ruined," Ms Kampusch now 18, was quoted as saying by the weekly magazine News.
“I always felt like a poor chicken in a hen house. You saw on TV how small my cell was - it was a place to despair."
She also told of her horror of being locked into her dark underground cell for the first time.
"I was very distraught and very angry," Natascha Kampusch, told Austrian public broadcaster ORF in her first televised interview since her escape.
Ms Kampusch repeatedly had to shut her eyes against the glare of TV studio lights, which ORF said were sensitive to light because she was confined to darkness for such a long time.
The 18-year-old said she bolted to freedom on 23rd of August while her captor busied himself with a mobile phone call.
Priklopil, a 44 year old communications technician killed himself within hours of her escape by jumping in front of a commuter train.
Ms Kampusch also said she would have gone crazy if her kidnapper hadn't occasionally allowed her upstairs, six months after she was abducted.
Early in her captivity, the teenager said she threw water bottles at the wall in frustration and despair.
The wheezing of a ventilator that pumped air into her cell was "unbearable," Ms Kampusch said in the interview, a 40-minute prerecorded account that gave Austrians their first glimpse of the young woman whose nightmare entranced the nation.
Since her escape, Ms Kampusch said she slipped away incognito to enjoy some ice cream.
"It was nice to smile at people, and no one recognised me," she said.
Earlier on Wednesday, News and the mass-circulation daily Kronen Zeitung published separate interviews in which Ms Kampusch said she once tried to jump out of Priklopil's car.
When Priklopil took her out on errands, "he always wanted me to walk in front of him, not behind him," apparently to minimise the chances of her escaping, she said.
Ms Kampusch told the newspaper how she attempted to leap from the car, but her abductor "held me back and then sped away."
Health concerns
The magazine said it interviewed the teenager at Vienna's General Hospital, where a cardiologist examined her for possible heart trouble.
She said she had suffered throughout her captivity from heart palpitations that at times made her dizzy and blurred her vision.
It was unclear whether she has been diagnosed with any chronic problems.
Ms Kampusch also said she often did not get enough to eat.
Another Austrian magazine, Profil, had reported that at the time of her escape she weighed just 42 kilograms - exactly her weight when she was taken on March 2, 1998, while walking to school.
Escape
Ms Kampusch called her escape from her captor's house in suburban Strasshof "completely spontaneous."
"I was there behind the gate to the garden and I felt dizzy. I realised for the first time how weak I really was," she said.
But Ms Kampusch added that she felt well enough - "physically, mentally and no heart problems" to make a run for it.
Once out on the street, "I saw a window open and someone busy in a kitchen, and I asked the woman to call the police," she said. At first, she said, the woman refused to let her inside: "She didn't want me to step on her lawn."
She said she wants to complete her high school education and is considering a range of possible careers, including journalism, psychology, acting and art, and that she has not yet decided whether to write a book about her ordeal.
Ms Kampusch also told the magazine she loved her parents, who divorced after she was taken, and denied there was any controversy.
