When the black dog has her claws hooked in you,
threatening to never let go,
trying to pull you under, into the darkness…
When the world is too loud, and too bright,
overwhelming all your senses,
pushing you to escape into the void…
When the night seems to go on forever,
dragging into the black,
until it seems even the stars have lost their light…
Then is when the sky will lighten,
Then is when the cloud-cover will dissipate,
Then is when the Dawn will come.
So, after the storm has raged,
go to where the Waters flow more freely now,
won and blessed for you,
and find your peace in nature.
Mist to Open. Mists to Bind. 
A lovely little prayer, I must say. I enjoyed it quite a bit.
