It's kind of like an overstimulation feeling in areas of bright light and then also having to focus on what different people are saying, and the ability to focus on their face. Something about looking directly at a person, it's like I see them-but I am not able to focus on them in the same way I used to. It's a little disorienting. Hard to explain! It feels like it has a lot to do with bright lights along with people.
I can't quite relate to depersonalization because I still have feelings and whatnot, but I do feel as though my perception is off and disorienting.
For me, my brain fog is made worse when I have brain pressure, so I included that as well. The Kudzu root helps because of it lowering my brain pressure as well.
Otherwise, my brain fog can make it difficult for me to function if it gets bad. I won't drive when my brain fog is bad, as I can't seem to be able to recognize "issues" when driving under those circumstances.
It's like my head is full of cotton or something, as it takes me longer to process many things. They do process, but it just takes a bit longer - the thicker my brain fog, the longer it takes for thoughts to process.
You said you can't focus properly on people - as in listening/hearing them, or in seeing them and recognizing them? If it's mainly stuff like that, it would likely be more of a depersonalization, rather than brain fog. With that, it's a matter of being in treatment that is effective for you long enough, as well as good detoxing.
That sounds more like sensitivity to external stimuli/sensory overload. It was one of the worst "symptoms" I had that is sooo much better now after a year of treatment. I couldn't handle motion either - not only could I not drive a car, I couldn't even ride in a car.
