What happened on your worst birthday?

I learned that the lump I'd had biopsied on my neck was a pair of thyroid tumors that were suspicious for cancer, and that the whole organ would need to be removed. After pathology, it turned out not to be malignant, which is lucky, but that was a pretty unpleasant few months and now I have to take thyroid replacement hormones for the rest of my life. The doc still hasn't got my dose quite right, so I just kind of low-key feel like shit all the time. It takes a couple months before we know if a new dosage is working better or worse. Hopefully they'll have it figured out by my next birthday...
