I believe I have CTE.

I have had sustained innumerable concussions over a long period of time. If i'm frank with myself, probably in the ballpark of 30, but who knows, maybe more. I'm anomalous in that I went out of my way to either get my head bashed in or do it myself (over and over and over and over and over and over). I've also been assaulted so many times (one-punch knockouts).
Very, very bad anger issues + alcohol was the cause of 90% of my head injuries. Can't take any of it back, though.

Neurologically, I am falling apart. Not even remotely the same person I was a mere year ago. Every day I seem to be getting worse. I am 33.

Lucky for me (wah wah wah), no one understands or cares, because who in the hell believes someone when they say they've suffered almost as many head injuries as they've been on this earth?

I don't think a few blows will cause CTE.
