If you're playing at a strong level the balls used can definetly change how the match is played. The US open balls are fairly light and have extra felt which fluffs up after a few games. In turn they end up playing slower and you are going to get a few more looks from the baseline and on return. Those US Open really do slow down after a few service games. It's not in your head, some balls play fast and others slow. You just have to learn how to adjust your game to different conditions. You're young and will figure it out. When playing with quick balls or in quicker conditions you might want to play a little more aggressive as you might not be able to defend the way you normally do. Start buying cans of the balls you most dislike so that you can get some practice and get over the mental hurdle.
Please excuse my punctuation and grammar.
