Where am I?

This is my first poem so don't be too harsh! :) There will be mistakes. Did this over Notepad.

Fragments of reality still ringing in my head,
A bullet through my heart, could it be? Am I not dead?
I blink twice, seeing if it may be true.
Flashbacks engulf my mind. All being about you.

I know I will never match up to what you desire.
Maybe I should have shot a little bit higher.
Thoughts of this love ending, a sight I cannot bare.
Coming home late, thinking I don't notice the smell of sin in your hair.

You run in the door, my worlds now spinning and gray.
Teardrops fall from your face. No more words I will say.
Blood falls from my chest, to a puddle on the floor.
The world turns to black. To my surprise I see a door.

I open that door wit caution, very slow.
I feel no pain, but suspense starts to grow.
A hatch opens up, so abruptly I fell,
Could it be? Did I end up in Hell?

A pit of fire, flames holding me so close.
I see a line of people, all melting in rows.
Now there is no doubt where I am.
Don't feel anything except for pain, I am damned.

My life is over, I have given all I had.
Given up in a world, a world so mad.
