I know that you didn't exactly invent the term unresolved trauma, BUT...

As a person with a lot of unresolved trauma (and perfectionism issues), I hate the term "unresolved trauma". I've been working hard with a therapist and a psychologist for years, and I've made a ton of progress, but my trauma will never be truly resolved. Every few years some new facet of damage will pop up that I won't expect and will have to work through.

It's a never ending process, and (imo) the term unresolved trauma implies that there should be a point where it becomes resolved. That's just not realistic or true for a lot of people.
