Emo? Emotional? Cutting?

Three words you never want to here from your best friend, son or daughter is the works, "I cut."  I am happy with my life, so I would never cut, but after serious thought over the subject I have concluded a reason for self harm.  Each cut is a very painful experience especially heart-breaking because someone is hurting themselves. I believe that the emotional pain they are feeling is confusing their body and so they associate it with physical harm by sawing at their skin.  While "sawing" may not be an appropriate word, I feel that it is very conveying and intense word choice.
