I think there are too many factors to account for to give a good answer.
But realistically: If the walled city was stable (relative to what I knowz I can only compare things to what I know and have experienced) and my life was alright or better then or course I would stay.
If I had kids in that city I would probably stay.
If it was a shitty life inside those walls, of course I would find a way to stealthily leave.
I wish you luck. And if I may, my recommendation to you is to look around in community groups for health care in your area or region. Take benefit of the collective effort in your region to find the persons or maybe even establishments who know and work with ADHD specifically
I am 31 years old. A lot of my friends aren't chasing partners, yet those who do don't really want to make babies due to the long array of problems affecting quality of life.
Thanks
