See the light behind the obstacles

I am inexistent, but in the eyes of those who UNDERSTAND, i exist.
I am evil, but to people who learned to dig dip WITHIN me, i became the definition of good.
I am numb, but to a few whom i learned to like and trust, i became the MOST SENSITIVE person they ever knew.
I am simple, yet complex.
I would be either be your FRIEND or ENEMY.
To the world i'm nothing, but to the lives i've touched, i may be EVERYTHING.
In whatever way you see me...
THANK YOU! :)
