Losing the plot

This expression always used to tickle my funny bone. Now it's not funny at all.

I am at the precipice of page 76 on a novel I need to deliver a draft of by May 1. Which means I have about 130 pages left, more or less. All of a sudden, I'm not sure what to do next. The outline I structured no longer fits and I am now at sea. There are a couple of directions I can take it, but once I take even one step forward, I must be committed as there is no turning back. That commitment is tough to find.

I must first see it...and then make it happen.
Not the other way around.
