The exact same thing happened to me, minus the crying though. I was more in a daze and felt nothing on my way back from the NCLEX. 75 questions, 2 hours, and I was certain I had to have failed. Afterward, it really was like being in some kind of feeling-less trance. Once I got home, I immediately tried that trick, and it worked as described!
A couple days later my name and license number were listed on the Mass.gov site!
The only thing is that I believe my popup message was a little different, but it started with "you have recently scheduled this exam" as well.
CONGRATS! You passed!! Now go celebrate already, you did it!!!
