[CFS-ME-Fibro] Anxiety attacks? Esogenous or endogenous?

[Guest guest]

Dear friends,

I was wondering if the anxiety attacks and depression in CFS/ME could be

considered primary at times instead of secondary. Or, put it in other words, is

anxiety and depression always related to the fact that a prolonged illness

lowers moods and gives anxiety or there could be different endogenous reasons

like bacterias, fungi, toxins and viruses crossing the brain barrier?

Cheers,

Massimo
