My epilepsy was the result of a car crash.
I was at fault in the car crash.
It’s interesting to be able to point to an exact “jackpot” event. 
So many people grind away at their memories trying to find a point of divergence where they could say “ah, if only that one thing hadn’t happened, everything would be fine.”
But even being able to identify an exact event doesn’t mean you can change it or that it’s ok to walk around with a chip on your shoulder. 
Wake up early, breathe the air outside and be thankful.
