CFS services have been established in Cumbria for two or three years,
they are currently based in Keswick.
As I understand it, the service they offer includes sending you for a
one off appointment with a consultant, and then offering CBT/GET. At
one stage I think they had an occupational therapist, which may be of
use to more severe sufferers, but I'm not sure whether this is still
available.
You might want to do some reading up before deciding whether to try
CBT/GET.
I haven't any personal experience of the service, so I'm limited in
what I can say about them. Perhaps other group members could comment...
