Went from: “Hey, I think I'm gonna be the Chip leader!” to “Hey, how come my screen closed” on the turn of one stupid card.

I decided on a whim to play the Big $16.50 this morning on stars, which, quite frankly is way out of my BR, but just wanted to take a shot.  Quite frankly, I was killing it.  It was one of those sessions you have where you start making reads without even trying, add to that some lucky cards, and some really bad play by some opponents and suddenly you're in the top 10% of feild.  Still early on, but after Late reg ended, I was feeling great, with a good size stack.  Then, this happened:
