SIV 

Acronym for: Self Inflicted Violence
Intentional harm of ones own body such as cutting, bruising and/or burning oneself. Hair-pulling, excessive biting of the skin to draw blood.
Point is this: You harm yourself intentionally in order to feel control of your life, to feel alive, or some other purpose.
Note this: it is an addictive behavior that can't just be gotten rid of; it takes a lot of effort and work. (trust me I know a lot about this)
