as someone that was also given an Rx for antidepressants due to a “fibromyalgia” diagnosis, it’s a working theory that one of the reasons for that disorder is, in fact, neurotransmitter dysregulation (e.g., norepinephrine) so that’s not completely off-base… sorry. it sucks, but it has to be eliminated as a mechanism. is it possible you have undiagnosed hEDS? that was the case with me, and a geneticist was able to sus it out. please google it, because if you’ve been diagnosed with fibro it means you have a vague nebula of symptoms that could be any number of things (e.g., lupus) and requires an extensive differential diagnosis which usually ends up being something else (if you’re anything like me).
