If you threw down that kind of cash on one spin of the wheel (remaining trip BR after an epic defeat at the tables), then I imagine you either have a severe temper issue or you're spreading blacks on blackjack. If it's the former, don't play any more until you can work this out. If the latter, why worry when you take a massive beating? If you're playing for these kind of stakes, you must be playing rated (I can't imagine the casino tolerating you otherwise), and nothing looks better for a rated AP than a massive red mark on their blackjack records. If your game is up to speed and you're confident in your ability, then embrace the negative variance and know that, now that you have that out of the way, you can probably look forward to your next positive swing.
