What do you think of my story...? =)?

What you've written, in my opinion, is quite good -- also well written in comparison to much of what I've read on Answers which was produced by young writers. I like your first line where you are questioning whether there is life after death; to me it expresses a philosophical introspection on the part of your protagonist. I think that the story has definite potential and is intriguing. I would like to know what will happen next, how the main character is going to deal with the apparent tragedy. My advice to you: Continue creating the story and see where it takes you. Good luck!
