yea some places out side the USA call DID by other names than we have here in the USA, here we dont have to take classes in .. structural dissociation... because we dont have a poly fragmented system for DID now. here all alters are viewed as equal and complete regardless of how they came into being, whether they branched off from another alter or from the body born and all those other issues that other countries outside the USA go by.

it would actually be harder for me to grasp the concept of structural dissociation because that concept isnt used here in my location. if I was talking in those terms and ways that are taught in that model my therapists and psychiatrists would end up misdiagnosing me. especially if I used the the terms that are taught in that concept. example the term tertiary in my location means from the times of the dinosaurs.

since 2013, and the change over to the new system here in the USA, if I now used that term in relation to my dissociation my treatment providers would think I was psychotic/ out of touch with reality. see what I mean... its best to go according to ones own location. with things like this.

for those with in the USA here is what EMDR is in the USA...

and this is what the USA treatment providers go through in learning how to use EMDR with their clients here

Im glad though that you and your location have finally found a therapy approach that works for you based on your own treatment plan and locations standards.
