I have TOEFL exam on saturday and i’m afraid i’ll mess up the speaking section

I have TOEFL exam on saturday and i’m afraid i’ll mess up the speaking section I have been stuttering for my whole life and it fucking sucks. I just sometimes imagine how life would be so much better if I never stuttered. Anyway, I’ve an upcoming exam on Saturday. I just hope I don’t mess up the speaking section because my stutter is kind of moderate-severe. And by the way is there any kind of pill I can take before the test? I never really took any medication for my stutter so yea i don’t really know. And wish me luck guys.
