I'm trying to take in the implications of it all myself - in a brain-fogged kind of way - and your post helped a lot. Will look at link tonight. I have definitely experienced transient but marked periods when the world goes dark , only to have it lift when I take an effective antibiotic or get out of a mold-compromised environment. One of my friends, who I have mentioned a number of times on PR, hung herself when in that state of mind, so I always bang on to people about understanding the depression can kill you quite effectively on its own unless you treat it, and respect its power. Hope yours lifts soon and permanently.
