I'm Fine (I Promise)

I hide the truth about my life,
The problems I've faced but not left behind,
But when you ask me why my smile doesn't shine,
I'll shake my head and say 'I'm fine'

I won't let anyone into my life,
Not even the person I claim to be mine,
But when you ask me why my smile doesn't shine,
I'll lie to you and say 'I'm fine'

I won't let anyone read my mind,
Especially when I'm at the end of the line,
But when you ask me why my smile doesn't shine,
I'll hold back a scream and say 'I'm fine'
