set over set again

Ran into another brutal set over set in a $1/$2 cash game and it's honestly messing with my head a bit. Had pocket eights on a dry board, guy calls my raise pre, turn comes and I catch the third eight, feel like I'm finally due for something nice. He slowplays his nines like a pro and, of course, I'm stacking off before I even realize it. Just stone dead unless I somehow fold top set, but I don’t see it happening.

People say it balances out long run but I swear these cold decks show up on a schedule for me. Been here before, and yeah, I get it, variance and all. Still, anyone actually manage to shrug these off or do you start seeing monsters every time you flop a set? How do you reset your brain after a session like this?
