If you talked about CFS in the UK, nobody would know what you are talking about. The articles in the Awake! didn't translate too well this side of the Atlantic. Anyway, ME and CFS are exactly the same.
To be honest, I think a lot of it stems from depression, feelings of inadequacy. I've often felt really down during my life - a total worthlessness feeling, i.e. I'm not the model witness my parents want me to be. This can make you feel genuinely ill - god knows it's certainly made me feel ill!
Anyway, these feelings of inadequacy can easily spiral down into illness. It seems more common with women. No wonder - I particularly feel for the sisters - they are so oppressed by their husbands and all that "headship" crap.
Agoraphobia is another one. Lots of brothers & sisters have that.
I want to make it clear that in no way do I feel their suffering isn't genuine - brothers and sisters in the hall often feel like that though - you can imagine the snidey comments can't you?
To be quite honest though, what is really wrong with a great deal of them is something they cannot say openly without getting into trouble. Giving it a medical title transfers the blame.
