MIA and her problems

So trying to form an outline to a novel about this chick called MIA and her problems with life isn't going as well as I thought it would be by now... I have a basic theory of why I can only write rather shortish stories: my plot line stinks and is way the frig too simple. So far the first chapter seems to look like a butchered attempt at a mass suicide, with crossed out words and blots of ink from where my pen exploded upon impact with the pristine white page.
And Mia... the name no longer fits the character I set for her. At this point I would probably be better of writing a series of short stories about her problems with life and the guy she has to call her boss. And so out of pure whim I shall name her Psyche, because she drives me crazy and what better word to describe someone who won't fit into a society made up of demons and humans underground.
