Who am I?

I am a mix of people's hopes But I can not fill those holes I am a half-smile or incomplete word A guitar without its chords I am a sentence without a period And the I in inferior I am the story behind scars Or the night without its stars I am the doubt and unfulfillment In the sound of your judgement I am the silence after questions Of a face without expression I am the space between lies Uncertainty in the eyes I am every step taken back When the sight becomes pitch-black
