I'm not sure if this is what you meant, but actually, being highly sensitive is not a diagnosis. It's a trait. It sounded to me like her T identified this trait in her.

I'm just quibbling a bit because to me calling it a diagnosis can contribute to the idea that being sensitive is bad, maladaptive, or in some other way weak. And I work hard to counter that with my clients an for myself.

I yam what I yam.
