First off, I'm not trying to be rude or anything, but I'd thought I'd point out a few things:
'She'd shot me' - 'I've been stabbed'
It seems obvious something isn't quite right there.
You could do with adding some more detail overall (E.G: I lay on the bus shelter, when a woman came up to me - I lay shivering on the cold seats of the bus shelter, only moving from the tight ball I had curled myself into when I caught sight of a woman heading toward me) Or something like that, you get the idea, more detail.
Also, the last few lines remind me of some lines from a tele show (Am I dead, in a coma....) Although that may just be me.
Overall it needs some editing and as I said, more detail, but the story line seems good, and it does make you want to keep reading the story.
(And don't have whole words in caps - DISABLED , DEAD - just have them normal.
