As someone with a family background in psychology (grandfather and three uncles who are psychologists, as well as two social workers in the family), let's dispel a few things here.
First, multiple personality disorder does not exist. However, the disorder that Herschel has been diagnosed with, Dissociative Identity Disorder, does exist. The most disturbing thing about DID is the first D, Dissociative. People who have DID are disassociating themselves from extremely traumatic events, usually brought on either by childhood abuse or severe trauma -- like combat -- later in life. Children can't handle severe physical or sexual abuse, so their psyches invent a new personality who takes the abuse for them. They are able to go away during it and come back when it's over. The result, of course, is alternate personalities who are not very well-adjusted at all.
Any Georgia fan who's tried to get an autograph or a handshake session with Herschel knows how reclusive the man is, and how little he craves the spotlight. I truly don't believe that he's Pete Rose-ing it here; I think he's genuinely trying to help other folks who have this disorder.
As someone who was once romantically involved with a person who suffers from DID, I can tell you for a fact that it exists and is frightening. Seeing it in action, seeing and hearing and literally feeling a person change into someone else, sometimes at the drop of a hat, sometimes several times within a short period, is a terrifying experience. Knowing what she knows now, I can assure you that the former Mrs. Walker is relieved more than anything to know that Herschel is sick, and that he can be treated and made better. What we should do is to send thoughts and prayers to Herschel and to be grateful that a family member -- a member of our extended Bulldog family -- is doing well and is recovering.
