Talks about suicide or death.
Children or adolescents may write or create pictures depicting or describing suicide/death.
Suggestive comments. If the student starts saying things like, "I won't have to worry about this much longer," or "Things will be different soon," it may not indicate optimism but intention to commit suicide.
Drug or alcohol abuse. Alcohol is implicated in over half of all suicides.
Putting things in order and "tying up loose ends." In children, it may take the form of cleaning their room (if it's not their habit), catching up on all their schoolwork, etc.
Giving away treasured objects.
Saying "I Love You" and good-bye.
Planning the suicide.
