Here I am, an Anagram

So here I am,
An anagram
 
I am manic, when I panic
Anxiety?
It frightens me
It's good to know all the days are nightmares
long ago it lingered
your dreams you would dream came true
 
Or did I dream to have a voila!
pierced in her violent violin
weave that song my muse, my mistress
 
Because here I am,
your Anagram
