Anyone else go on insane losing streaks and question everything?

I swear lately it feels like every session turns into a magic trick where my stack just disappears. I'll get a couple hands that look decent preflop, play them right, but still end up watching the chips drain out. Makes me question if my whole approach is out of date or if the cards just hate me this month.

I've gone down rabbit holes reading about variance and sample sizes but man, in the moment, it's hard not to think I'm doing something dumb. Anyone ever found a way to snap out of these funks, or do you just keep grinding and hope the tide turns?
