Who?

This is kind of an introspective deep down poem. Like two sides of me are vying for dominance.

You are the bane of my existence
You are the reason I keep going in life
You are the voice in my head
Causing me to look at some things differently
You help me up
You drop me
I love to hate you
And
Hate to love you
I turn to you in times of need
Turn away when you ask me to stay
We are two sides of the same coin
Yin
To my Yang
Salt
To my Pepper
Dominant
To my submissive
Submissive
To my Dominant
You are an enigma
Wrapped up in me
The puzzle
You are You
I am Me
Who are we?

Author's Note

I am going to revamp this poem, but I do ask that you ask me before borrowing, and you explain in what way you will use it.
