In my family, it is genetic. We did not all have "trauma" together or separate from one another. As I aged, I noticed the symptoms more but I can think back and now see that I've always had it (my mom sees this in herself too). I remember in my teen years that I could never get past a certain "fitness" level; I always leveled out even though I tried to build more muscle. Still the same today. When puberty hit, I needed a lot of sleep. I was always in bed by 8:30 p.m. I also had sleep issues throughout my childhood and still do. I sleep deep but am not rested. Unfortunately fibro is rampant in my family and I always tried to find "similar" experiences that might have caused it but have come to the conclusion that it is genetic.
