You've done a great job here of mixing real life (depression or illness, perhaps?) with the mythological, and you've done it with a good poetic sense. Your phrasing is one of the best and more original I've come across on this site. I especially liked
"I never want you to be Orpheus
Asking every devil for my face"
and your image of a serpent in your head.
I did notice you spelled "biting" with two t's. I'm not sure if maybe it's just a different spelling, like color v colour, but I did notice it. Also, was "god's cry" referring to one god or many? It could work either way, I just wasn't sure.
Anyway, I really liked this. I think I'll go read some more!
