I rather doubt such a strict dichotomy could stand much critical scrutiny.
Regarding biological connections to personality traits, it's common to think that genetic expression is only a matter of having particular sequential patterns in nucleotides inherited from parents. But, things aren't that simple.
For example, epigenetic events--chemical alterations to DNA by methylations, phosphorylation, etc, which are personal acquisitions, also alter what RNA is transcribed and what protein segments get tailored and sewn together, and the subset of stuff that's actually dong work is quite different in composition from what's possibly produced by DNA within chromosomes.
Molecular biologists are really in the early days of understanding how being exposed to environmental conditions/stimulus might alter mechanisms of cellular function to create different capacities of cellular receptivity and response, and collectively variations in tissue/organ structure and function. Neurobiologists' trail behind that vanguard. What is clear is that organisms are not mechanisms solely defined by the DNA blueprint their parents gift them.
I understand that the content of your post is an expression of your personal experience.
My point is really more general, and on the nature of "what is supportive?" As I've written in this group many times...support is a tricky thing, yet, understanding support is an underlying requisite of this group.
My reply is in this thread because it is a reaction to the subject line of your post--which calls out to others to talk about their bravery relative to mental illness. Your subject line communicates an expectation that stories of bravely confronting mental illness are out there among readers of this group. That is an expectation about shared experience--the stuff of culture.
Our culture has all manner of vernacular knowledge about what's good or bad for the ill, mentally and otherwise, and derivations on those rules that serve as standards of performance about how to acceptably conform while ill. Being patient, hopeful, brave etc are such expectations.
If you look over the history of posts/replies in this group, you'll see both affirming expressions to conformity to cultural expectation and histories wherein apparent attempts to manifest conformity to expectations became painful sources of distress.
