The Multiple Personality Disorder of Herschel according to his book, wife and doctor.

The man is sick and it is documented. Are his supporters just as sick? Mental Illness should be treated, not exploited.

Mental illness is real and serious and deserves treatment but add head inuries on to that and you need a person under constant observation and not in the Senate.

Breaking Free: My Life with Dissociative Identity Disorder Paperback – Illustrated, January 13, 2009

Walker reportedly suffers from Dissociative Identity Disorder, formerly known as multiple personality disorder, which Grossman claimed surfaced during their marriage.

She told ABC News in 2008 that she didn't know what Walker was going through at the time as he shifted from a football career to ballet and the military.

In Walker's tell-all book, Breaking Free, he revealed he suffers from a mental illness, but it wasn't until he saw a therapist that they could identify the problem.

Walker's therapist, Jerry Mungadze, told the outlet that he had met Walker's alternate personalities during their therapy sessions.

"They will come out and say, I am so-and-so. I'm here to tell you Herschel is not doing too good ... When he finishes, it would just disappear back in him, and Herschel comes out," Mungadze said.

Grossman recalled an incident while she was pregnant and claimed her then-husband told her: "Close the door. I am having bad thoughts. I am thinking I am going to hurt you."

We were talking and the next thing I knew, he just kind of raged and he got a gun and put it to my temple," she claimed.

She said she came to believe that it was one of Walker's alternate personalities who were in control during that moment.

"There was somebody there that was evil," she said.

Walker told the outlet he had no memory of the event, nor does he remember winning the Heisman Trophy in 1982.

Although he said he doesn't remember the events, Walker didn't deny doing it. "No, I don't remember that," he said, adding: "but I probably did it."
