Constant

You are the only constant in my life
You are my angel and my demon
You are my joy and sorrow
However your presence has brought me no joy recently
You have turned into my poison, slowly chewing away on my soul and spitting it out
You carry a poison tipped dagger and every time you stab me with it I feel the poison course through my body, its corrosive nature slowly tearing apart my soul
And each time you withdraw your dagger I feel sorrow because even though you are slowly killing me, you are also leaving me and if the price of being close to you is my death then I will gratefully except that price
