IT

It is something that cannot be seen,
It is something that lingers within me.
It is a lie that everyone believes,
It is the smile on my face which decieves.
It is that voice in the back of my head,
It is the one that says I'd be better off dead.
It is something that haunts me when I'm asleep and awake,
I just don't know what it real and what's fake.
It is the thing that has made me this way,
It is what makes me suffer through the day.
It is something only I seem to see,
And now..It? It has become me.
