An ex-girlfriend is also quoted:
The woman, a flight stewardess named only as Maria W., said Andreas Lubitz told her he was receiving psychiatric treatment and would wake up distressed in the night during their five-month relationship in 2014.
She was quoted by the German newspaper Bild as recalling how Lubitz would change when he talked about the pressures and conditions of his job.
"He never talked much about his illness, only that he was in psychiatric treatment,” she said.
"We always talked a lot about work and then he became a different person. He became upset about the conditions we worked under: too little money, fear of losing the contract, too much pressure."
