Hmmm... I would say that you have described Paranoia very well and you did an excellent job in the overall idea of what you got across in the poem. I thought though that it didn't flow at parts for some odd reason which could just mean I need to read it more but that's what I got. Anyway you had a good word choice in this poem as well as a overall great idea of what to write about. Good job and keep writing.

Your language placement certainly captured well some of the jagged, and colorful, edges of that
of which you speak...

(...and then,) there IS the 'old saying':

"Just because you're paranoid doesn't mean they're not after you.."

and the opposite of paranoia is?.............
