I am hypothyroid - apparently I have Hashomoto's. I only take synthetic thyroxine at the moment. I have recently had a busier than usual week due to my husband being away. So I was the only 'taxi service' for the kids and had to deal with various other things including a long drive to a funeral, school stuff, and all the household things my husband would normally deal with etc etc. It felt like a really tough week, even though I'm not currently working. I was glad when my husband got back two days ago, but since then I seem to have gone to pieces, feeling weak and on the verge of sleep all the time. One endocrinologist once told me ages ago that the more you do the more thyroid homones you need. Is this actually true and does it mean that if you are busier than normal you might well feel bad afterwards? And does anyone else experience this?
