I'm sorry--that sounds like an awful problem. Maybe the issue is you have so few limitations--no deadlines, no pressure, no constraints--that there's nothing to check your intellectual fixations. Photography is as much visceral as intellectual--it's a process and an art. Why don't you plan an exhibition somewhere--it doesn't matter where as long as you have a firm date. Plan a trip away from home for a photographic project as the subject of the exhibition. So you might have a week to come back with 16 images--and you have to deal with editing, printing, matting, and framing before the show. Creativity means coming up with a lot of ideas---practicing, practicing--to produce a small number of exceptional works. Almost no artists (with a few notable exceptions) work with your current model.
