Getting the groove back...

After getting the wind knocked out of your sails, when nothing seems quite so important as it did before, how do you get your groove back?
I've been taking my WIP to work with me and editing on my lunch our and any down time I may have. I work in a cubical now (love it!) and I'm pretty much out of sight from the powers that be so when I have nothing to do I pull out the old WIP and go at it. (or sometimes I go blogging)
But it's been a bad week and now when I look at my WIP -- I don't like any of it. I fight not to throw the whole thing in the trash because I'm guessing this might be a carry over of feelings from the bad week.
I think I need a good romance novel. Something with nice thoughts and happy endings. Something to lift my overall mood.
I had it.
But I lost it.
Take a break?
Or keep plugging along feeling like someone stuck pins under your finger nails?
What do you do when life throws you down?
