Hello. Would you please tell me what the underlined sentence means in this context below.
I don't follow why the writer use "there is" in the sentence.
Please help. Thank you.
----------------from a children's novel, Honest Truth by Dan Germeinhart
I thought about what was coming. About what I was walking toward, up ahead there in the clouds.
About where I was going, and what I was doing.
I was every different kind of sad there is. And every kind of determined, too.
In all that I thought of, I never thought of stopping.
I was so lost in thought I didn't notice when the truck pulled up beside me and slowed down.
He felt every kind of sadness that exists.
