Trapping One's Inner Voice

In this world, there are so many bad things. When I was little, whenever I saw a bad guy suffered, I felt pity. I didn't judge him for what he's done, I wasn't angry, I knew everyone got a second chance. All I had was mercy.
As I grew up, that inner voice faded, being pushed away by this evil world. Reality came in, the bad guys got what they deserve. They did bad things, and when I saw them suffer, I would say, "no wonder".
One day... when I was down, and all I did is stayed in my room... contemplating... A familiar voice was again heard--the sound of my heart. She came back in my solitude, and I was listening.

This girl in the picture symbolizes my inner voice, the purest part of my soul, being chained and gagged so that she cannot speak to bring my sanity back. I've thrown her away to the deepest part of my heart, ignoring her, becoming more like the evil world. But one time of solitude brought her back. She is speaking. I am listening.

 This is my entry for 's contest: What makes you sad?
Well, what makes me sad is losing my inner voice, trapping her to the deepest part of my heart.
