The damage does not end when the hit does.

For years, I believed the symptoms were separate problems: memory, mood, focus, anger, exhaustion, identity. Eventually I had to consider that football, boxing, mixed martial arts and repeated head impacts might be part of the same story.

TBI or CTE: What the Hell Is Wrong with Me? is my attempt to document that story honestly. It is personal experience, not medical advice. It includes what I noticed, what frightened me, what I tried, what helped, what failed and why I decided silence was no longer useful.
