I just saw that @Action for M.E. directs people to the BACME website on their guide for management, which they've been encouraging people to direct their doctors to: https://www.actionforme.org.uk/health-and-care-professionals/primary-care/treatment-and-management/
Don't have the energy to wade through the document but I see them referring to CBT and GET as the go-to trial. Way to get people sicker.
