You are the conquering hero!
When I was finally diagnosed after decades and decades of being told it was all in my head, I considered it a triumph of my will over all those medical “professionals” who were so quick to dismiss me. I seriously considered putting together a letter of some sort to send to some of my past doctors pointing out how obvious my symptoms were, and how dumb they were for missing the diagnosis. I didn’t, of course. I have more productive things on which to spend my time.
Knowledge is power. Spread this power lavishly in all the corners of your life.
