Both are correct, they say different things.

If all you left with was nothing you left with. But there you had to do.

“all

I took with me you left only”(you left): nothing. What I could know?

What do you feel

you are left with, nothing to do?

All

you even have is nothing. all you have is nothing. words must be done to show up as nothing. means: You can’t do anything for nothing. means: All you have is nothing. means: Everything is what you have now.

and it sounds like you previously did have something.,

not something you don’t know.
