Roadblocks, logjams, tangled threads...

I have a million things to say but can't get the thoughts out. I feel like there's a block in my mouth, my throat, or in this case, my fingers - everything wants to come out simultaneously and the channel is just not wide enough, so they're all piling up, pushing on me, on each other. Like a logjam.

Or maybe it's like a huge tangle of thread. All I need to do is find an end to start with, and the rest will start to flow. Now, where's that thread end?

Frustrating.
