Have you seen a doctor about the possibility of chronic fatigue syndrome. Cfs is a neurological disorder the hallmarks of which are profound, bone crushing exhaustion that is not relived by rest, neurocognitive problems marked by memory problems, concentration problems, and problems with aphasia (wrong word).
Intolerance to cold, cold hands and feet, tinnunitus (buzzing) and coordination problems are also common symptoms of this disorder. Did you cardiologist do a tilt test? It sounds like you might want to check into the possibility of orthostatic intolerance.
It sounds like your doctors have looked into the most obvious areas which is good. Sounds like it is time to look at some other options.
It is very common for doctors who cannot find the obvious to tell a patient that their symptoms are all in their head (duh, this is a neurological disorder g.93) and suggest that you relax.
While relaxation and reduced stress are worthy goals for all of us incuding our doctors, they do not cure organic illness. If you aren't familiar with a good cfs doctor in your area, try the co-cure good doctor's list. The website below has far more information than I have given here. You may wish to take a look. There are many other good sites, but steer clear of any that suggest a psychological process is at work unless you need to hear more of what your doctors are already trying to suggest. Pamela hahn also has a good site at the about.Com sites.
p.S. Aphasia is pathological not a product of tenseness. :roll:
there is no cure for cfs, however, your symptoms can be managed.
Best of luck
