Ok, looking through your labs there is some missing, as you pointed out.
Your high BUN and HCT could indicate some liver issues, so you may want to investigate that further. Most weightlifters have some elevated liver markers, but I don't remember if HCT is one of them. Though I doubt this is the cause of your issues.
Your TSH looks good--you can get further thyroid testing if you are inclined, but probably not worth the effort.
Your total estrogens may seem a bit higher than optimal, but its very hard to interpret these--as you pointed out, E2 is the test that you actually need.
T is low. You should test LH/FSH to see if they are getting a signal. If they are low, you could try a clomid restart or HCG monotherapy. If they are higher, then you are most likely primary and will require exogenous Test.
At 42, you are at the age where many men are experiencing these types of symptoms and issues. A lot of docs will be sympathetic to it at your age (versus someone in their 20's with the exact same problems) so you probably won't have trouble finding a doc to treat you if you want to just go on T. Finding a doctor that can treat you optimally may be a little trickier, but if you take the time to learn here and ask questions you will be well ahead of the curve and be able to become your own advocate.
