Self-harm is intentionally causing harm to ones own body. This is commonly seen in people who have depression or have experienced trauma. The kind of self harm that is typical is "cutting" (C.)
A. Burning skin with heated objects
C. Cutting or sticking skin with sharp object
D. Bruising yourself with a heavy object
^^^These are all intentional injuries and are therefore self-harm examples
