Kinda Like This: When It Wears Off

I've either made this post already or thought about doing so much I've done it...at least in my head...but even if I've mentioned this before it's worth repeating simply for this incredible example of beautifully written dialogue:

RIVER
Going. Going back, like the apple
bits coming back up. Chaos.

SIMON
But you felt okay this morning...

RIVER
(smiles)
Played with Kaylee, the sun came out
and I walked on my feet, heard with
my ears...
(crumbling)
I hate the bits, the bits that stay
down and I work, I function like I'm
a girl. I hate it because I know
it'll go away, the sun goes dark and
chaos is come again. Bits. Fluids.
(really crying now)
What am I?

I've tried numerous times, using thousands of useless words, to describe what it's like to feel the medicine, that keeps me functioning like a normal person in this world, wearing off. Joss Whedon, the writer responsible for the aforequoted lovely bit of dialogue (I think) nails it in one succinct interchange.

The key line for me, the one that digs at my heart every time I hear River say it:

"I hate it because I know it'll go away...the sun goes dark and chaos is come again."

Because for me, regarding the medicine, it is so true.
