"Brain fog" is difficult or embarassing to explain/justify to others. I probably come across as lazy, because I am always in a fog or daze, and cannot get tasks done on time. I always take naps, which makes me look lazy. Saying, "I'm sorry, I have a mysterious disease that hinders my cognitive abilities and makes me very tired" isn't very well understood by most people, and just looks like an excuse to not do things. But I literally cannot function normally. I am frustrated with myself for not being as productive as I should be.
My sister thinks I am exagerrating and it's in my head. It is true that it's in my head - these "head symptoms" are interferring with my life..it is probably not just a food problem causing my symptoms. I have cavity prone teeth as well, which I have to do something about. She told me it is my fault that I haven't gotten my health problems solved yet, which is partially true. But my family thinks everything will be cured if I see as many doctors as possible, and I know that is not true.
