Since you know some of the emotions that are common to those with DID, or even those without DID who have suffered similar traumas, the best treatment that can be used by therapists OR the person with DID/PTSD or those in their circle, is Thought Field Therapy. Using a combination of psychological approach (identifying and focusing on the traumatic thought or feeling) while tapping on a specific sequence of energy meridian points, the feeling recedes in the moment and over time.

This therapy works, it works fast, has no side effects except feeling better, and the treated feeling state does not seem to recur, although similar feeling states may continue to occur until treated.
