Penthouse to the outhouse. Some guys cannot handle the shift - may even get "loans" from the wrong people. I understand it can be difficult, so it's always important to remain grounded, even when everything is coming up roses.

Anyone making the point that he “couldn’t handle the swings”* should in the same breath note that the “swings” that first threw him off his game were not mere variance, not recklessness, and certainly not bad play, but the outright cheating on Ultimate Bet. The kind of loss in confidence that would come from literally every move you make being optimally countered by someone who can see your hole cards every hand and cutting your bankroll by millions while you struggle to fix a strategy that isn’t broken would destroy most if not all of us for a long time.
