i know how it feels to think there is no end to the run bad, but when it hurts this bad, regardless of the BR it is probably too high for you to be playing. there have been plenty of times where i have known i was +ev at a game but wasnt rolled for you, and honestly right now Im realizing that its better to be comfortable with what you are playing than to be playing the highest stakes you can.

all i can say would be pick a single game that you enjoy, study it as much as you play, and play the stakes where a downswing doesnt affect you. its easier said than done, but with good volume, even small stakes can make a good amount.
