I think that for me it's a kind of gateway diagnosis. If I can get it, they will help me with the other symptoms. I'm okay with occasionally feeling dizzy. It' just digestive symptoms and some unpleasant but not dangerous ones like malaise and fevers. They are suggestive of autonomic dysfunction but in order for them to rule out eating disorder completely (I don't have one, I'm a teenager who lost weight, they are convinced I'm anorexic despite all of the symptoms) and get some actual treatment, I need to somehow prove that I have POTS even though I probably don't which is scary. I only very occasionally get head rushes and I don't think it affects my life enough to warrant a diagnosis.
