Hidden behind my smile

What you don't see,
When I say I'm fine.

What you don't see
When I fake a smile.

Every thing I want to say,
But never had the guts.

My smile lies to you,
And you trust every lie.

Outside my smile is bright,
Inside my soul is dark.

The tears I never cry,
Slowly kill me.

Just because I'm strong,
Doesn't make me invisible.
