He hopes its publication will change the public's image of the disorder and encourage people suffering from the illness to get help.
"D.I.D. is not 'Sybil' or 'Three Faces of Eve.' D.I.D. is just an illness that people are dealing with," Walker said.
In "Breaking Free," Walker wrote, "I feel the greatest achievement of my life will be to tell the world my truth."
