Yeah definitely. Really appreciate your sceptical of the psycho/functional stuff too. I find some schools of medicine have a big ego to assume anything we can’t figure out must be psychological and not that we just haven’t figured out what’s wrong yet.
It’s a common story in medicine. From peptic ulcer to lupus, illnesses thought to be psychosomatic or “hysteria” turning out to be genuine physical illnesses.
And patients with psychological issues tend to realise their issues are psychological in nature and vice versa. Although both have downstream effects. And in my above example. The psychological burden of thinking you have (having) a debilitating psychical illness but being disbelieved by your doctors must be enormous.
