"Valley of unrest" is profound... I like how you leave the reader with this phrase and how it is the title as well.
My only suggestions:
"The day it rushes by"
- Comma after "day"?
"With the sun &all your tears"
- Liked the mixture of sun and tears here, it was unique and abstract as I usually don't think of them so close together.
Neat write, you have a fresh style and I enjoy your brevity the more I read it!! Take care.
