Underneath this smile

Underneath this smile,
There are feelings i never show.
The smile and laughs i fake each day,
I'm sure you'd never know.
Underneath this smile,
my world is crashing down.
But i keep it locked inside,
so no one can see,
what its really like in me.
Underneath this smile,
is a shattered and broken heart,
I'm trying to pick up the pieces,
but i don't know where to start..
