Depression is a mental state characterized by feelings of inadequacy and lack of activity that children describe as feeling sad all the time. Self-harm includes intentionally harming one's body through acts like cutting, burning, or bone breaking. Suicide is intentionally killing oneself, which some religions view as selfish. These behaviors can be caused by factors like poverty, abuse, genetics, substance abuse, or illnesses. People self-harm to feel something when feeling numb, and people commit suicide because they feel trapped in a world they despise and cannot live in.
