I can relate to not knowing what "normal" is. Sometimes I wish I could spend a few minutes inside the head a neurotypical, a bipolar person experiencing mania, and a bipolar person experiencing depression so that I could directly compare experiences and know exactly where I stood, symptom severity-wise. But that would only be touching the surface, as I would be observing static states, and so much of my bipolar experience involves fast cycling. Yeah, I'd also like to peek inside of the heads of people with uncomplicated borderline disorder and ADHD....
Can the term "normal" even be applied to something that cannot be directly measured, like subjective psychological experiences?
