Someone Missing

Forever gone,
Like yesterday,
Been missing for so long.
Wonder if anyone will see,
That I'm right in front of them.
I guess I'm air,
You can sense but not see me.
Gone like trash,
Never missed,
So easily thrown away.
Can't compare to me,
For I am not here,
You can't see me.
Screaming like a roaring lion,
Dying of its last precious breath,
And now you've defined,
The true meaning of being deaf.
When will you notice that I'm hurt...
Do I have to kill someone you love the most?
