I have only visited Terri's site once.
My cohorts are mostly other nurses, who went into nursing like me to take care of and treat patients in order to assist them to live at their highest level of function possible. This is highly individualized, but I do not remember anyone guaranteeing that this life would be all sweetness and light. We just tried to make it that way for our patients.
Unfortunately, or maybe not, according to your view we have mostly left the field. I do not regret it, because of the negative trends that are taking place.
I visited it daily, even signed the guestbook. Still visit to this very day.
