I am currently in high school and I am a good tennis player. Last year I took a break from tennis and when I came back I had to train vigorously to get back to my form.
Now the coach wants to put me back in the team and sets up challenge matches for me. I know I am better than the people I play but I always seem to lose.
Does loosing a match mean you are better? Your technique might look better when hitting for practice. But a game is more than technique and practice.
Maybe for now get your Mind game up to par as Tomaz teaches it. If you play to win than better technique is only a little part and when you play better players, there technique will be most likely even to yours, what than??
Tennis Tactiques, Mind and Emotional Control seem to be the step you have to focus on, without knowing more about you.
Hope that helps. Stay calm , stay focus , dont critic yourself , bounce , hit. Good luck
