3. The common stimulus in suicide is psychological pain.
The suicidal person is seeking to escape pain. Suicide can be understood as a movement toward cessation of consciousness and a movement away from intolerable and unacceptable pain.
5. The common emotion in suicide is hopelessness-helplessness.
A pervasive sense of hopelessness, defined in terms of pessimistic expectations about the future, is even more important than other forms of negative emotion, such as anger and depression, in predicting suicidal behaviour. The suicidal person is convinced that absolutely nothing can be done to improve his or her situation; no one else can help.
