With or Without

I am nothing without
But everything with
And if I knew nothing about
I only wish it were a myth

It was what gave me confidence to
Do all I have to get where I am
But now it has left along with You
I feel left behind like my life in a jam

Should I carry on alone?
Or do I need it
More than I really know?
I ask, fallen in this pit.

I have no hand to help me now
I have no support to help me out
I don't know whether to be up or down
I guess it is something I can't be without
