Won both sets with my partner but feel shit

So played a random game, won first set 6-2, second set tie breaker, but idk today I felt so weird, I felt sloppy, late reaction time, racket slipping, I’ve recently changed my racket to drop shot, played the first game and it was amazing, but today I felt off and then my stupid mind thinking racket sounds different, it was my second game, and I thought maybe it’s off because I left it in the car under the sun so perhaps damaged yesterday (Inside my bag ofc)
