I've not been working on my latest WIP for a while now. Possibly because it's rubbish, but mainly because I've been cramped with the dreaded Writer's Block.

Or have I?

The reason I'm finding it tough to go forwards is because I don't know how the blooming thing's going to end. I know how it's supposed to end. But I can't come up with a magical moment that's a)satisfactory, and b)plausible. And by magical moment, I mean the bit where your reader says... Wow!

So my question to you, is, does Writer's Block exist? Or is it just a symptom of bad plotting? Or something altogether worse.
