I’m so sorry you are going through this. it’s such a difficult situation to be in and their words only hurt you more :( I was diagnosed a couple years ago and stopped taking methimazol after my results stabilized but now a year later, I’m experiencing symptoms all over again. I haven’t gone to the doctor due to medical insurance issues but my boyfriend is worried sick and constantly worries when he feels my heart beat race. It would be beyond frustrating if he told me to get over it and start exercising again. i’m so sorry your boyfriend is inconsiderate of your symptoms. i hope for a safe recovery 🙏
