There's some evidence that cognitive therapy combined with gradually increasing activity can help sometimes.
Mental therapy while trying to increase ability to exercise
My friend was just diagnosed with Chronic Fatigue Syndrome but I don't know much about it. It's characterized by long term fatigue and other symptoms, and it severely limits a person's ability to live a normal life. What are the other symptoms? I don't really know, but the fatigue that is felt is not due to exertion or a previous medical problem. That sounds awful. I wonder how common it is? Not sure, but there is no real cure there is limited treatment. What is the treatment? I can't say. I the US there are no approved medications or procedures. So, is there nothing at all that can be done?
Evidence suggests that cognitive behavioral therapy and a gradual increase in activity suited to individual capacity can be beneficial in some cases.
