In Part Eleven Angela’s own words on the consequences of TBI. http://tbivoices.com/blog/uncategorized/from-a-butterfly-to-a-tbi-survivor/
In another of Angela’s essays, she analogizes her post brain injury transformation to that of a caterpillar to a butterfly, but in reverse. Her musing traverses the question of whether she is starting over in a metamorphous, or is permanently trapped in the form of a “horn worm”, a being that will never transform to the butterfly, or whether this is just another in life’s long intermediate stages.
That’s the most elegant explanation of change after TBI that I’ve heard.
