" Suicidal thought is a symptom of illness, of something else gone wrong. Most suicides are not impulsive, spur -of-the-moment decisions at all. Instead, most of these deaths are the result of a person losing a long and painful battle against their own impaired thinking. A suicidal person is someone who is unable to tolerate their suffering any longer. Even if she does not really want to die, she knows death will end that suffering once and for all. "
