Street/Beat rambling wordplay

I need to tell someone
But no one can I confide
An omnipresent observer
Whispering silently inside
I want to hide but my presence is implied
Always being watched my hands always tied
Being taken for a ride without a place to hide
Inside I hear rambling banter and clamor
Is it my doppelganger
A pathogen of anger
Attacking my sanity in cryptic profanity
It’s a Goddam calamity
Is it real or just a fantasy I’m panicking in agony
And he just keeps on nagging me
Dragging me and stabbing me
Shredding my brain and shagging me
…….Oh the humanity
Ripping apart my fragile mind
A voice so darkly unkind
The humiliation the exploitation
No alleviation from the cranial castration
From the brazen maven of invasion
Comes salvation
That omnipresent silent observer
Puts me in a fervor
Silently cursing and perverting me
Hurting and converting me
Churning and burning tossing and turning
Then deserting me
Always watching and waiting
Hating and debasing
My head is rotating and pulsating
So Goddam frustrating
I just want him to leave
Die and let me grieve in peaceful reverie
Give me one full day of brevity
Instead of bleeding in severity
But he stays and misbehaves
Maybe its I who should cease
Not take life any further
But I just stay and gleam away
In the eyes of my observer
