Brain fog was my first ever obvious cfs symptom and the one that lead me to do my research. It gradually got worse over time and nobody would understand if I tried to describe it to them. Yesterday I watched a video of Serena Summers: and she mentioned that her brain fog is accompanied by depersonalization and derealization. Since brain fog still is a consistent problem for me that rarely gets better and really bothers me since I still go to school full time, I looked it up. I meet the criteria in many aspects. I always feel hazy and kind of drunk. My vision sometimes feels way to sharp and lights get really bright but I can't really see still. When I'm outside in the sun or inside with the lights on I feel the worst. It's very hard to describe. A very dream like feeling. It's like I'm living in a constant bubble and I feel very disconnected to the outside world. Things said to me sometimes feel like they go through a wall first before they reach me. My movements also feel weird sometimes. Especially since my brain fog got a lot better a few months ago after years, I really feel the difference now since it's back again. I finally felt somewhat in touch with the world, like I'm actually living in it and can experience and process all the stimuli. I know this can be triggered by anxiety, which I definitely have. I got some sort of social anxiety. But this developed due to the brain fog I think. Because I never fully felt like I was in that outside world which is horrible being in school and having to talk in front of people. I'm also experiencing emotional numbness lately. Sometimes I feel like I should cry (I cry about everything normally, it's just a release of tension for me) but lately I can't. I also don't really care about people close to me as much or staying in contact with them (I'm acting as if I would though, because I know it's not normal and I also know how I would usually act). I'm not unhappy though. I'm neither happy or sad, just in a very neutral state. Right now my anxiety is very weird... it's actually sky high sometimes (at least I know it would be) but then I'm just numb (I guess the purpose of the numbness is to shut the anxiety down). Now I'm really confused if depersonalization etc. is common with me/cfs and brain fog. Is it a normal part of brain fog even? Does anyone have the same experience?
