I never understood people who self mutilated themselves. But yesterday I accidentally burnt myself with my lighter and it hurt and that felt good. Not the burn but a feeling any feeling. So I can easily see someone hurting themselves over over again just to feel. You may say that sounds stupid I feel all the time but that's just you not everyone feels the same as you do. Some of us wear masks. A smile on your face but underneath behind the mask it's a whole other semi-feeling human being. And it's a good thing we wear that mask because if we unleashed the human it surely would become survival of the fittest.  I think we deaden our nerves because we felt too much and the needs could never be satisfied.  So we supress. Then are shocked when we feel again.  Some may loose control for a chase.  I can only imagine how many go primal.  We are only human animals of this earth.
