I found this manuscript on EBV testing in the Journal of Clinical Microbiology
I read through it quickly and tried to figure out how to interpret your results in light of what the paper says but quickly got lost. For instance, your IgG antibodies for EBV are elevated but the paper says that they often stay elevated in anyone who has ever had EBV.
Assuming your doctor is right and the results show a persistent infection, that sure could account for your fatigue. At the same time, EBV could be one of several infections your body is now fighting. Once the body gets bogged down fighting one infection, other opportunistic infections can either come out of hiding or be contracted more easily.
The good news is that Valtrex (or just plain acyclovir) disrupt EBV replication and has been shown to have significant clinical benefits for CFS patients with active EBV infections. Your doctor might be sending you to a psychiatrist because he's unaware that treatment for EBV exists. It is very very common, unfortunately, for doctors to do this kind of thing to patients with your symptoms once they realize (even mistakenly) that they can't do anything for you. By dismissing the symptoms as potentially neuropsychiatric or just psychological, they can feel better about failing to treat and can write you off as another head case.
Several alternatives to Rx antivirals exist, as well. One is to do a Google search for a company called Researched Nutritionals (this is NOT a sales pitch for them). I mention them only because they are one of the few places on the planet where one can still obtain EBV-specific transfer factors. These are immune molecules that attach to pathogens on cells infected with EBV and flag them for destruction. Very very powerful but can trigger significant worsening of symptoms during the die-off phase early in treatment.
Sometimes it's better to start with things that kill/disable viruses first before ratcheting up the immune system with something like transfer factors. I'm not sure if the products Cumanda and Lauricidin (totally different products from different companies) are effective against EBV but I think they are. A quick Google search would turn that up.
Anyway, the good news is that you have lab results that support a viral basis for your condition. The best way to find out if that's what's causing it is to fight the EBV and see if you improve!!
Best of luck with your health and please post updates to let us know how you're doing.
