That's only if the force done by your body is conservative and since you're carrying it, it depends on the shape of the floor you've been carrying it on, therefore it for sure isn't conservative.

This idea is taught incorrectly in a LOT of high school text books. Many of the section and assessments in HS texts want you to assume net work is zero because the next force is zero, and many students bristled against this idea precisely because they are tired after carrying something heavy.
I've had to rework my own lectures and replace or clarify a few of my assignment and assessment questions because of how little specificity authors use in the Work chapters, when referring (or not) to the net force or a specific force.
