Understanding the Real Meaning

Isn't it funny,
How it doesn't make a sound?
How you didn't know you'd lost it,
until pieces had been found?

Isn't it weird,
How you couldn't ever tell?
How a smile on the surface,
didn't mean escaping hell?

Isn't it sad,
How you're accustomed to the rain,
How anger has taken over,
you've grown to love to the pain?

Isn't it scary,
That while you were crying,
You never even noticed,
How your soul was literally dying?
