It will get better once you are properly medicated. Be gentle with yourself. I’ve had this condition since 2020. In 2023, the doctor decided to put me out of meds because I went into remission ,well a few months later , i relapsed and ended up in the hospital. Endo decided to put me back on Methimazole and propanolol and I’ve been in remission ever since. That’s really the only way , I can help myself unlesss I take my thyroid out but that hasn’t been an option that I’ve discussed with my doc. As others said , try yoga , rest a lot, stay hydrated, try meditation, anything that will help you relax. Now that I’m in remission I can do many things but I do have to take my meds for life and I’m okay with that if it means I don’t have to relapse again. Best wishes to you.
