Learning Past Cause vs. Quality of Present Life?

Reading our posts, I see two populations or maybe three. There are those of us who, like Hercule Poirot, try to solve the mystery of what caused their PN. Then there are those of us who are more concerned with what might be done to lessen pain and slow––if not stop––the progression of their PN. There is a third group of us who try to do a little of both. Each pursuit can become a preoccupation, a preoccupation that can be really time-consuming. When I first got my diagnosis of idiopathic peripheral neuropathy, I thought only about How can be possible? What had I done wrong? Was it some long-ago injury? Poor diet? Could others in my family have had PN? Today I think less about those things and more about what I am doing in the here & now to manage my symptoms such as they are (chiefly terrible balance). I still think about what may have caused my PN (possibly my years of hard drinking when I was in my 20s and 30s?), but mostly I'm thinking about what I can do today to lessen PN's intrusion on my day. I was wondering how others divide their time in thinking about their PN. More about what may have caused it? More about what you can do to make your life more livable today? Or a little of both?
