Almost all of my worst memories of school evolve around gym class.
I'll never get over it. I HATED team sports all through school (except for soccer). Not so much because I was inept, but because the @#$% teachers never explained the damned rules. Being a boy, everyone assumed you knew every detail intimately from birth. Excuse me. My parents came from Europe; they were never into North American team sports. No one ever coached me.
Sorry, baseball65, but baseball was the absolute worst. It put me on the spot, everyone yelled at me for doing the wrong thing or striking out or fumbling the ball. Charlie Brown in person. I was the last choice when teams were picked. Really bad for the ol' self-esteem.
Can I blame some of my TMS on this? Sounds logical. Phys ed was physical, after all. It was definitely a source of conscious and unconscious rage. Rage against my parents. Rage against my friends who made me feel like a loser. Rage against the school system. I get all worked up just thinking about it, even though it was decades ago. It turned me off sports for life.
Although I never really embarassed myself playing sports, I could see how anxiety about being humiliated in Gym or on a ballfield could lead to TMS. -Al
