"I won't ***** you over."

For once in my life,
I need this to be real.
You know my past and present
understand how it might feel.
I know your situation
and I know it in and out
But despite it all I can't help but feel
That I'm only around from partial desperation.
I mean not this so harsh
But it's the bold reality
I'm so scared that you could leave a permanent laceration.
You can tear me apart
Without using your hands
You can take control of me
With such simple demands
I am scared that I might end up the puppet
and not the puppeteer
So please don't let me down
I have given you it all
If you choose to fail me,
Just simply let me drown.
