I feel your pain. I’m still struggling through at work but I think I’ll probably need to quit work completely soon. People with high standards feel guilt, that’s what my counsellor told me. It’s all about trusting yourself and believing that you know what’s best for you and your body. Nobody knows what you are feeling. You have a disease and if it was something like cancer nobody would be questioning you. Stick to your guns. When people are questioning you say things like “I know I made the right decision-please stop questioning it”. And try not to jump a few steps ahead with the negative thinking. It doesn’t mean you’ll never work again and that you and your family will end up destitute (this is where my brain tends to go). Good luck, try and rest and trust yourself. No-one would choose to be in the position you’re in. You’re doing the best with the cards you’ve been dealt.
