No

Not in my experience, I still get severe flashes. The main things I have found that help are coping mechanisms and a social safety net

I would say yes, it eventually gets better, but learning what it is, learning to recognize symptoms, and learning good coping and self help skills help.

from what I know the clinical wisdom is that as long as you treat the problem in some way (i.e. antibiotics, immunomodulation) it can stabilize as you develop but if left untreated this is less likely

Mine kind of did. I used to have constant symptoms and Attacks but as I’ve gotten older, I really only get attacks when I’m extremely stressed out
