In the space of 30 minutes and less than 100 hands I lost 10 buyins.

Why did you keep re-buying, or were you already up more than 10 buyins?

Generally, I don't subscribe to the stop loss or stop win philosophy, but I will quit when my stack is gone. Yes, I know that mathematically your next hand is your next hand, whether you play it here and now, or in two weeks at a different table.

You've got to play through the downs to get to the ups, but that all assumes that you are playing your best game all the way through. Once you start getting your brains beat in on the order you described, I don't know too many people who are playing their best game. Get some distance. Take a break at least.

Also, it sounds like you are taking your downswings kind of hard. This is part of the game. If you can't deal with it, maybe different level? different hobby?
