rushing

Hey guys, I think I’ve asked this question before. If I have, then I’m still feeling rushed when playing in a topspin rally. Everything is just too fast for me to adapt and I cannot react in time and start rushing every shot. I lose so many points like this and its getting really frustrating because I’m not getting the match results I want. When I do try to take my time, it’s often a low quality shot which the opponent hits the ball by me leaving me again confused and frustrated at what’s happening. What would you guys recommend me to do next?
