Editing Andreas Lubitz (section)

===Mental health===

Lubitz suffered a relapse of depression just before Christmas of 2014. The relapse began with symptoms of psychosis. The main symptom was a powerful and unfounded fear, that he was going blind. Lubitz contacted over 40 doctors about this, but none were able to cover any problems with his vision nor his fear of the same. He also would complain that he was having hallucinations where he would see flying insects, flashes of light, stars, streaks and halos. He was also suffering from light sensitivity and double vision, as well as being tormented by insomnia. By early March, Lubitz, terrified by the idea that his eventual blindness would cost him his pilot's license, he became suicidal and he began searching the internet for ways to commit suicide on his laptop.

In the days before the plane crash, Lubitz had been treated for suicidal tendencies by doctors and he was declared "unfit to fly". The doctors gave him several sick notes and advised him not to fly again, but he simply ignored their advises. On March 20, a new method of suicide came to Lubitz' mind, as he searched the internet for information about the locking mechanism on cockpit doors. On March 22, the day before returning to work, he wrote “Decision Sunday,” along with the flight code BCN, for Barcelona, on a scrap of notebook paper that was later retrieved from the trash in his apartment. Below that heading, Lubitz listed several options: “find the inner will to work and continue to live,” “deal with stress and sleeplessness,” “let myself go.”
