I'm not sure I should write this response. But, I'm going to.
Stop comparing your life - yourself - to others. That's very important. I know thyroid sucks, I've had it all my life. But, if I spent all my time looking at others and comparing myself to them, I'd never have time to live my own life.
It doesn't matter what other people have and you don't have - or, come to that, what you have and others don't - it's not a competition. You do the best you can with what you've got.
Took me a long time to learn that lesson, but I married a man who lived his life as if all the world had been invited to a party, except him. He was bitter and twisted. And, I saw how futile that was. He could never fill his life because he was always looking round to see what other people had, and did. Yes, he had health challenges - life's not fair - but instead of trying to over-come those challenges, he just sat and complained about them, about how life had treated him so badly. Well, life treats a lot of people badly. In fact, it probably treats everyone badly in one way or another but we don't always see it. We've got to concentrate on the good, and not the bad. Have a rant and a moan, by all means, but then chin up, shoulders back and carry on.
And, now, you can tell me I'm being rude, and unsympathetic, and whatever you like! It's ok. I know I am. But, attitude is everything!
And, now down to practicalities! You over-did it yesterday, used up all your T3, which you cannot easily replace, and now you're paying the price. We have to learn to pace ourselves, I'm afraid. You are not taking enough T3 to support all that activity. Especially when you're not used to it. So, now, make a cup of tea, put your feet up, and watch something funny on the telly. And, next time you feel good, take it easy and enjoy it. The housework is not going to run away.
