So I have a good serve. It's not huge but I can place it and sometimes put some extra steam on it. I have always struggled with it but now it's really good. I serve really well in clinic and practice ( like 80 percent) and today during a match I completely stunk. Doubled every serve except I think 3. And the serve was going everywhere. I wasn missing just deep. Short, deep, left, right. Omg. Was atrocious. Please help. Then I totally derailed and lost confidence and got in my own way. I am a 4.0. Lost 1-1. Sooooooo upset and embarrassed.
