Seeing the Forest Despite the Trees

I'm lost in the woods. Seriously lost. I am at that point in the WIP that I have gotten in so deep in the story that I know where I need to go, but my path is obscured due to all the damn trees. I've laid out my clues, and know the backstory for all of my characters. The problem is, I may be losing sight of my story. I am trying so hard to tie up the threads I've started and make my characters motivations believable that the big picture is starting to look more like a Monet painting than a crisp, digital photograph. I need to find a way to see the forest despite the trees.  Help!
