sm

Self mutilation. When someone physically injures themselves to rid or relieve themselves of mental pain.

A highly addictive practice, as when the body is physically injured it releases endorphins into your brain and blocks mental stress. Similar to the "high" you get after virgerous excercise.

Just because you sm doesn't mean that you are suicidal, or have any wish to die whatsoever.

A very common and usually well hidden practice.
