Thing1 was diagnosed with an autoimmune disorder almost 2 years ago now. We knew the diagnosis would come with big changes to his life, and this winter we really got to understand what it means to live with and care for someone with a chronic illness.We were still somewhat prepared for it.What we weren’t prepared for was going through very similar routine with Thing2. After several months of ER visits and tests and flu‘s, we now find ourselves between a number of diagnoses, including a possible tickborne illness. Thing2 has found himself and completely unfamiliar territory. My superhero whose used to jumping over tall rock piles in a single bound it’s only found himself with barely enough energy to walk from chair to bedroom.Except during the worst of the pain, however, he still my superhero. I still see his enigmatic little smile, and he still finds ways to experiment, even if it’s only with making movies with special on the iPad (full disclosure: I could not do it) or testing theories about how your atoms are not really touching your brother that he heard on Cosmos (science hurts sometimes).I would donate an organ if I could make him better tomorrow, by doing so, but, as Thing1 has Learned over last year, what doesn’t kill you doesn’t just make you stronger, it also makes you smarter.
