My biggest mistake was considering my "Fibromyalgia" as my DIAGNOSIS...the final word... instead of considering it as a set of symptoms....a symptom of a larger picture. My biggest mistake was always researching "Fibromyalgia" and "Chronic Fatigue Syndrome". My biggest mistake was thinking that a virus had caused my fibromyalgia. My biggest mistake was not researching my biggest symptoms.....pain, fatigue, insominia, brain fog. When I started considering my fibromyalgia as a symptom, not a diagnosis, I found my answer, and now I am getting better.
