...so I want to know why this has happened.
You know, I had such experiences several times when you write almost an essay, and then... it took you 40 minutes to write that essay, and then you understand you were logged off the Web site, and have to sign in again, and you are disappointed, and so on...
In such case, just think that omnipotent God did not want that post to appear, and be grateful to Him that it is not here
Just let these feelengs go, relax, and just as you recommended - be grateful, and begin responding to other people.
