I received my first concussion in the 7th grade, at the skatepark. I was knocked out cold for almost two minutes. I had also been stung by a stingray while surfing earlier that morning (great day). I don’t know if I ever felt quite the same after the concussion. The splitting headaches lasted a few weeks — the mental side effects, and generally altered sense of well-being — much longer. I can genuinely relate to everything you wrote. I hope you’re doing better — thanks for the article. You’re a great writer.
