you could look at my Dublin Ireland post, alot of it is UK organizations. From your location, searches may turn up more precise local information.
sorry the search is really jumbled.
i notice that valuable contacts about N support and treatment are under the heading "Mental Health". oh well, they have to list it somewhere. If you look at those networks and sites, and organizations you will reach someone who knows enough to know N is not "in our head" and not behavioral.
