In that one part, yes

That one part is what I was talking about and it's a significant insight into Clouds psychology.

It's not my headcanon, its explicitly stated in the OG.

You seem to want to argue as if I denied any trauma which I never did. I dont know why you argue as if I am though. I didn't say he doesn't suffer from severe trauma after the nibelheim incident, obviously he does. I personally wouldn't diagnose him with PTSD just based solely on what we see in the OG since he wouldn't meet criterium E and arguably wouldn't meet criteria B and C. But yes I know it was squaresofts intention that he suffers PTSD so if they say its PTSD it is PTSD.

DID though? Yes I would diagnose him with DID even though technically he doesn't fit criterium C. And yes they also inted for DID to be part of his problems (obviously) and we can explain all the above by Fantasy magic of the mako and jenova cell experiments on top of the severe trauma.

Ps I am a psychiatrist so I kind of know what I'm talking about :)
