When the demons come

Though I understand
that creativity, like water,
probably constitutes
about 80% of my psyche,
these days it mostly feels
like breathing underwater.
And on those rare occasions
when the possibilities bubble up,
it's only a matter of time
before the demons come
in their waterproof gear
to suck the life and joy
out of those brief visions,
to expose the dirt and grime
that lie beneath.
Please tell me
this is not my swan song...
