The woman - named only as Mandy K - was mauled and bitten by the polar bears after climbing over safety walls and swimming out to meet them at feeding time. She was saved when zoo keepers pushed away one of the animals when it attacked her.
The keepers' bravery was praised after they dragged the 32-year-old German mother out of a moat for the animals. They had to shove the animal out of the way after one of four polar bears dived into the water and attacked her, inflicting serious bites to her legs and arms.
On Monday it emerged that she is a teacher who had been driven to despair by her failure to find a job.
Her former boyfriend - identified only as Lars, the Danish father of her seven-year-old daughter - said: "She loved caring for kids and really enjoyed all the special trips that she could arrange for them like going waterskiing in summer and swimming after school.
"It really affected her when she lost her job and she just couldn't see any future," he added.
The couple separated four years ago and share custody of their daughter, who was spending Easter with her father.
Mandy remains in intensive care at the Virchow Hospital, where she has severe bite wounds.
Doctors said that there is still a high risk of infection and she remains in a critical condition.
Lars said on Sunday: "She was supposed to be joining us today for an Easter egg hunt. I don't know what we will tell our daughter."
