I'm not angry
I think I'm not angry because I'm not losing money. If I did, I think I would be angry
Although anger is not exactly the right reaction. It's better not to get angry but to analyse your game, your bankroll management and the situation in general.
I always go through options 1 and 2 where the first one I feel when I make the best choices and lose to variance and the second one when I play the wrong way. The third option in my case does not exist.
