MY PCP diagnosed me with GAD. My symptoms: anxiety (of course) and non-restful sleep and fatigue. Now what I am really scared of is that this might be what some would say is chronic fatigue syndrome, which in my research is rather hopeless. GAD? Not so much. I've had anxiety in the past, to the extent that I really considered *****. I went on Lexapro and came out of it. This time I'm doing the same. The thing that is different this time is my trouble with sleep. I sleep but its light, not restful. It is this that leads to fatigue (I think).
