I've been experiencing what I've called "Brain fog" for over 2 and a half years now and have recently come across the term "derealization", which fits to a tee. The only problem is, I don't have anxiety/panic attacks. And if I do, my anxiety is mild. Anxiety does make sense because I worry a lot, think I have some underlying disease that is causing this brain fog/derealization, and other symptoms I've found to be a match by during those vague online tests (desperate, can you tell?) but nothing clear cut. I have never had a panic attack, and the derealization is constant rather than coming and going with bouts of stress. Is it still possible that this constant symptom could be related to anxiety, and should I pursue it in this direction or search elsewhere?
