Aren all suicidal people crazy?
No, having suicidal thoughts does not imply that you are crazy, or necessarily mentally ill. People who attempt suicide are often acutely distressed and the vast majority are depressed to some extent. This depression may be either a reactive depression which is an entirely normal reaction to difficult circumstances, or may be an endogenous depression which is the result of a diagnosable mental illness with other underlying causes. It may also be a combination of the two. The question of mental illness is a difficult one because both these kinds of depression may have similar symptoms and effects. Furthermore, the exact definition of depression as a diagnosable mental illnesses (i.e. clinical depression) tends to be somewhat fluid and inexact, so whether a person who is distressed enough to attempt suicide would be diagnosed as suffering from clinical depression may vary in different peoples opinions, and may also vary between cultures.
