The Void In My Life

I don't think that I can function without you.
You give me the strength to do the things I do.
I know having you in my life is wrong.
My will power of letting things go just isn't that strong.
I can''t nor don't want to let you go,
but having you in my life has got me so low.
Low at my cash and low at my weight.
But you in my life sometimes seems great.
At times you make me feel so high.
Other times you make me just sit and cry.
You drive me crazy but at the same time keep me sane.
I know I should break free from all of your pain.
Maybe you are feeling some sort of void,
but eventually my life you will have destroyed.
