Have you tried walking around each day as this "enhanced" version of you, sort of living in her skin and seeing things as she does? This may give you some new ideas. Not that your daily life itself would necessarily be fodder for the story, but you may find yourself making connections and finding bases for extensions that could be useful.
The evolution of your processes/world view could be intergrated into the work, I would think. Depending on where you are in the writing, and of course with me not knowing the details of your story, I think a similar transformation in your character could be interesting.
Do you know how your story will end? I've heard of writers working backwards when they get stuck, at least for a while.
Musician Brian Eno compiled a classic series of cards called the Oblique Strategies, designed to assist the creative process when one gets stuck or needs fresh perspective. This is a link to an electronic version of the cards:
Oblique Strategies There is also an app for iPhone, though there are a number of substandard imposters. If you check this latter option out, make sure it's the Eno/Schmidt version, released by Squarevibe.
