One of the most annoying traits of fibromyalgia is the fibro fog. I suffer from mental illness too . The fog I like to call it brain fog . It's mostly just annoying . Although when it's mixed-up with the psychotic part of the things I deal with it is more like my brain is confused about life . I have a feeling of kind of like dissociation . If anyone can understand my post and has experienced this please let me know. And what you do about it.
