I can completely, completely understand. I recently went through the same thing. I was even about to sell all my gear and replace it with new gear as a 'fix'. Something to bring a spark back to my photography.
In the end I didn't.
What I did do though is to try something new.
I went and spent a few bucks on some bits and pieces from Bunnings. Set up a space in my office to shoot some close-quarters "studio"-ish stuff. Something I'd never tried before.
It served two purposes; It allowed me to try something new, and it also allowed me to do some photography work without actually having to go anywhere (I'm a lazy bugger).

My point being; go try something new with your gear. Macro, Abstract (I'm not creative enough for this), or whatever?
Just a thought anyway.....
