This captures anxiety quite well I think. The feeling is like a storm, you know it's coming but you just can't stop it. All you can do is try and ride it out.
Like crawling black monsters
the big clouds tap at my window,
their shooting liquid fingers slide
over the staring panes
and merge on the red wall.
Some of the fingers pull at the hinges
and whisper insistently: “Let us come in,
the cruel wind whips and drives us
till we are sore and in despair.”
But I cannot harbor the big crawling black clouds,
I cannot save them from the angry wind.
In a tiny crevice of my aching heart
there is a big storm brewing
and loud clamour and constant prayer
for the reflection of snow-capped mountains
on a distant lake.
Tires and dazed I sit on a bear skin
and timidly listen to the concert of storms.
