I suggest two or more tablespoons daily of colloidal gold daily for your depression and brain fog. I can personally attest to colloidal gold increasing mood, focus and memory - and tests as well as anecdotal evidence have demonstrated the benefits of colloidal gold. Check out the article I researched and wrote about colloidal gold:

I can appreciate extreme fatigue - I battle that myself due to the damnable Lyrica I take for diabetic peripheral neuropathy (which I am addressing naturally and hoping to ultimately reverse). Three things I take that noticeably increase my energy are the outstanding all around nutritional product IntraMax (which has a whopping 415 different nutrients), OxyActin (which contains anaeropbic oxygen as well as CoEnzyme CoQ10) and a supplement that is a combination of Vitamin B12 nd folic acid. Without those, it would frankly be very difficult to drag myself to the computer every day.

Since Whipple disease is "a systemic disease most likely caused by a gram-positive bacterium, Tropheryma whippelii", you might be able to defeat it with lots and lots of colloidal silver. Insofar as headaches go, the best remedy I know of for headaches is plain old pure vanilla extract - couple of teaspoons in a glass of water. Next best is turmeric/curcumin, which might also help your health in many other ways - one of them being that it is a very good natural anti-inflammatory.
