Confusion and Giving Up

I was suprisingly happy when I wrote this; You'll see what I mean when you read it.

Why am I here?
Do I even have a purpose?
I know that it's near,
But I can't seem to touch the surface.

Am I insane?
No, just confused;
This kind of game
Leaves me hurt and abused.

I feel insignificant;
Like I don't matter.
Why waste all this time spent
On pointless chatter?

No one understands my mind,
So who would care
If I got left behind
In my dark little square?

The darkness is closing in;
It won't let me loose.
I know it's a sin,
What I'm doing with this noose.

Now, it's done;
I've made a mistake.
The pain's only just begun,
My soul to break.
