Except for the part with her dying i feel like your story is exactly how i lived only months ago. This is a very realistic story, and thank you for writing it.
When I started reading I was kind of reading at a slow kind of pace and then as I went on I began speeding up because there was so much intensity in your words. This was really loaded for a one-shot, I think. Reading the end of it I was really shocked and awed. I feel like it was a bit much but it's a one-shot, it's your story and there was so much emotion within the story I didn't really care.
I loved your description too, the last three lines were probably the best in my opinion, they just really stood out to me. I enjoyed reading this.
