Yet another of our "I think it's important to remember this" posts.
Whether trauma causes a CDD or not isn't actually about its severity. It's about the nature of the effects.
We Crew, particularly us Willows, have been through what we would consider, for ourselves, severe trauma, compounded by severe neglect and lack of any significant kind of support. But it didn't cause our plurality, other things did - other things that we are keenly, fully aware of.
And yet people with other kinds of trauma that feels, to us, less horrific, nevertheless is enough to have caused them to have a CDD.
Remember, there isn't really an objective scale of trauma, because trauma is not the event. It's the reaction to it.
Our reaction, plurality wise, to our trauma was to draw closer together, to unite against our common enemy. It didn't push us apart.
Other people's reaction to their trauma pushed them into separate pieces, or separate selves.
I think we do a disservice to many pwCDDs by saying that CDDs are a result of severe trauma - it encourages trauma Olympics, it encourages dismissal of trauma because other people "had it worse", so why are you so strongly affected by this more "minor" thing? When honestly it doesn't matter how culturally, socially, or personally seen as severe it is. All that matters is how it affected you. And not even in the sense that it matters how "strongly" it affected you, but in what particular way.
If your trauma caused primary structural dissociation, that's PTSD. If your trauma caused secondary structural dissociation, that's CPTSD. If it caused tertiary structural dissociation, that's a CDD.
THAT'S what we should be talking about, not severity of trauma.
