On downswing at NL10 - Losing to Donks

keep playing your game

Yup, just keep playing your game. Don't start doing anything stupid. Don't go crazy with your hands.
It might be good to post some of the hands to make sure there is nothing you could have done better. If you played the hands perfectly, then just forget about it. Downswings will happen to everyone and fish will keep on playing with confusing lines, but you will get your money back in the end.
I have had many days when I have lost more than that 6 buy-ins you lost in 4 days. Try to stay positive and play well

Only thing you could do is to avoid bluffing against fishy players and go for value bets more.
The rest is playing your own game like the rest already saying.

Hi, 6BI is really nothing mate, that can happen in two days easily ;). I remember that when I experienced it for the first time I was really upset about it myself, so I guess it gets better with experience. No worries, it will get better. If u feel tilted, u can go play nl5 for a couple of hands or take a day or two off.
