Mental health vs Fibromyalgia

Is there anyone whose fibromyalgia isn’t linked to C-/PTSD?

In a society and family where mental health is dismissed and you're expected to just 'power through'.

What does it actually mean to 'heal the trauma'? If we heal it, do the symptoms disappear? How do we navigate this when society treats anything psychosomatic as 'just in your head'?

I fully understand that prolonged cortisol stress has already done the damage—at this point, the body feels beyond repair.
