Wild pitch

I’ve had this issue:

For the first 25 pitches im perfectly on, but once i make 1 mistake, all of my control goes. whats happening?

My guess is you worry too much about making a mistake, that somehow you’ve become convinced that after the first twenty-five pitches or so you’re going to screw up—and that’s what happens. Let’s look at that a minute—what kind of mistake are you sure you’re going to make? What are you convinced you’re going to do that will affect your control? I would want to know more about this, and then I could tell you a couple of things that might help. :?:
