Personally i didn’t really have performance anxiety, but I would get really pumped every match with my pulse racing and sometimes even my hands shaking afterwards. I always had to take breaks in between ladder games, only after an hour or two it would normalize enough to queue repeatedly.

The cheese didnt bother me much, I always loved macro and did that every game behind good scouting, often leading to some timing attack I built up to like a stim bio timing or tank marine drop.
