In about March of 2018, I was crushed by chronic fatigue, anxiety, and brain fog. Testing revealed that I had Lyme disease and a variety of co-infections. I ended up spending close to $10K and tried tons of therapies including intravenous, light, sauna, antibiotics, etc. These are the things that worked for me. Definitely get a smart doctor on it and also do your own research.

Testing for Lyme Toxins
Lyme, especially when active produces neurotoxins. These toxins may produce brain fog, chronic fatigue, and other neurological difficulties. A good way to test if these toxins or mold toxins are creating problems for your nervous system/brain is the Visual Contract Sensitivity Test. I use this one: https://www.vcstest.com. As you eliminate the toxins and reduce the bacterial load, your testing and symptoms should improve so retesting can help.
All research suggests that 21 days of doxycycline or similar is recommended.
Get Plenty of Sunlight
This was the biggest game changer for me. LOTS of sunlight. Sunlight can be highly effective for the body. The most important sunlight to get is sunrise and in the middle of the day. If you are highly sick, stay in the sun as often as possible with 75% of the body exposed and no sun screen. Slowly build up your capacity for sun. Your body will adjust and burn less.
