I notice a few things... but really I cannot comment on everything.

Your MCV is just almost out of range. That indicates poor B12 status.

Your B12 is marginal, and you could try 1 mg a day of methycobalamin for a while and see if that helps. 400pg/ml is the new low and you are hovering over that. If you were on the way down when that test was done, you could be below it now.

Your white cells are quite low. B12 can help that a bit, but also it might indicate that your are fighting some kind of virus. White counts may go down if you have a viral illness. (your EBV titres were elevated).

The TSH of 3.31 is normal on a the old scale of .1- 5.0..but the new scale you would be just out of range and mildly hypo as the new scale ends at 3.0. Not all doctors use the new scale however.

You might think about getting a DNA test for methylation capability. Some of our posters here have done that and all of them showed genetic errors. I am beginning to think when people show up here with stubborn symptoms and a genetic panel would be helpful. 23andme.com offers this for $99.
The FDA will not let them "evaluate" the results but they do give you the results so you can look them up yourself.
