Has she seen a doctor about that?
Right now, I’m rolling with her hypothesis that it’s purely environmental, and finish our intercontinental move next week.
Honestly, I don’t hold out hope, but at least our destination country is one with a good cultural attitude to mental health, which I’m hoping may rub off on her. And me - I come from the “keep calm and carry on” school, often to my detriment.
I come from a faith culture where seeking mental healthcare is both a sign of weakness and lack of faith. Instead you must first pray it away. Meanwhile I'm surrounded by so many "professional" faith based councilors that it's hard to find providers who take religious trauma seriously.
