I think a principle of emotional processing is that once you get behind you stay behind. It’s like an email in-box, although of course vastly more complex.
An issue with Developmental Trauma is that there are feelings that are just too big to feel, so some part of you develops a workaround. Ever after, it is highly tempting to keep using that workaround. This is more or less what Personality Disorders are. They are all related and in my view have their roots, most of the time, in the first couple years of life, and the mother/child bond.
Yes, MOTHER/child. We humans have been doing things a certain way for many millions of years. It is the same way the rest of the animal kingdom does it. This does not change for reasons of political convenience.
