All of the traits you’ve described also very much fit PTSD as well.
To me taking a Watsonian approach to the character we she a woman who was forcibly taken by the Borg and assimilated at a very young age, then years later ripped away from that as well. That’s two extremely traumatic events( that we know of). Then following on we see the character years later at a point where she has somewhat worked though those traumas.
A Doyalist reading we can say it was the 90s and discussions around neuro-divergency and more general mental health were far less common in media. So we’re probably both over reading things.
You may be right, the more of Voyager I watch the more flexible each character appears in order to fit around what the story requires. Apart from Tom Paris repeatedly being an idiot, that’s a constant.
We can agree to disagree and enjoy it on our own terms I guess. If I have been dismissive of your argument I would like to apologise, that was not my intention.
