Hmmm...
I think you need to realize that you are not your "disfigurement due to an accident".
An accident is just that: a chance happening. At 6, no one should have been doing other than loving you as the little boy you were.
Apparently, that didn't happen. And you seem to be a sensitive soul, so I would posit that you felt whatever the response was or was not more keenly than others might.
The result--intended or not--is that you have real feelings which surround the "disfigurement" and which affect you, even now.
Is that about right, so far?
