In dark moments I continued to wonder if the wrongness was me. Perhaps it was a problem of character that made me feel this way. I didn’t believe this to be true, but I had no explanations for my symptoms and little corroboration in my lab work. I still wonder if patients with a well-understood disease feel this way. Are these questions particular to—and intensified by—uncertainty, or are they a feature of any ongoing experience of ill health? Or both?
