Awaiting an Ending

I keep hitting roadblocks on this Great Big Project. All I want is for it to be done, for it to make sense and come together on its own. And it's nearly there, but a few final bits have to be thought out. It's getting to the point when for a few moments I just want to scrap the entire thing, but stray beliefs in its overall strength prevent that. I have other ideas I could be doing instead. Songs, stories, travels. But - oh, blast - I owe it to these characters to give them an ending. They've been waiting for it for two years now.
