I try

You know its true Mistress!

I tried to be just what you need
I hope you know I'm trying
I think you want what I can give
I wish your heart would take it
I put myself out all alone
Wanting you to pull me in
You leave me there
Not ready to help
Not able yet
To save me
Who needs who the most
I think its me
My need to save you
Whatever it takes
Whatever you want
I long to do for you
But,
The one thing that your asking for
I don't want to give...time
