She believed herself to be completely normal. Two very simple reasons lay behind her decision to die, and she was sure that, were she to leave a note explaining, many people would agree with her.
The first reason: everything in her life was the same and, once her youth was gone, it would be downhill all the way, with old age beginning to leave irreversible marks, the onset of illness, the departure of friends. She would gain nothing by continuing to live; indeed, the likelihood of suffering only increased.
  The second reason was more philosophical: Veronika read the newspapers, watched TV, and she was aware of what was going on in the world. Everything was wrong, and she had no way of putting things right - that gave her a sense of complete powerlessness.
