To live without it would be painful.

Even though Music lets me know emotions, and 

Family reminds me of bloodline and support...

It'd still be aching if I didn't have it.

A cell phone can always be replaced.

The internet won't always be there.

A warm bed won't always be welcoming.

Books can be replaced with imagination if you're willing to.

But, if I didn't have that one thing, what would I do?

I can't live without a voice.

I can't live without a say in anything.

Without a voice, I wouldn't be able to express myself truthfully.

I wouldn't be complete.

A voice is the most powerful source; I can't live without it.
