The diabetes wasn't a shock - VERY strong family history. It was inevitable - my cousin is next up on the family list. Every descendant of my maternal grandfather who is my age or older has it. I'm the first in my generation.
The Hashimoto's shouldn't have been a shock - but my parents forgot to tell me about my father's diagnosis with hypothyroidism. It (Hashi's) is also fairly strongly genetic. That one hit me out of the blue - but it may explain my daughter's 2 autoimmune disorders. I was not previously aware of a family history of autoimmune disorders.
Overall, it was more angry-making than a shock - angry that I haven't had time to care for myself properly since my daughter's second autoimmune disorder was diagnosed 8 years ago. I'd hoped I'd get a breather to fix my life up before the inevitable hit. C'est la vie.
The first thing I always do when I get a new diagnosis (personal or - more often - family) is find a good online support forum, both for support and education. Forums like this one have been - literally in my daughter's case - life-saving. It took me a while to find this forum - after two wrong turns into other forums (one mostly dead & the other run by a (recently-deposed) bully (not that I had anything to do with the bully being deposed
). I found this this forum while I was temporarily forum-homeless. I'd hesitated to join it before because I didn't want to intrude on a primarily European forum - but I needed an online home for my learning stages so I mostly figured out how to convert my US numbers to your numbers, and here I am. This is a much healthier forum than the two I first encountered.
So - the upshot of my long-winded comment is that (based on too many years of experience in medical forums) you're in very good company here!
