I remember those days well, but I waited so long to be diagnosed, I had no idea what was going on with me. I would cry over everything, and often be unable to stop! While the tapazole helped a lot of my hyperactive symptoms, I felt just as emotionally out of control while on it. I was very glad to be off the medication after my TT. Things are much better now, I am back to being my old emotional self - meaning I still cry at the drop of a hat, but it isn't so out of control. I have always been a crier, just my nature.
Maybe if you show your family some of these posts, they'll start to understand it isn't you, it is the disease and the drugs. At the very least, know you aren't the only one to go through this, you aren't crazy even though it might feel that way.
Good luck to you.
I'll not consider RAI unless everything else failed. usually, RAI is not an immediate option, most people wait for 2 years before doing that (unless you have a special need for RAI, for example, cancer..)
You might be experiencing anxiety or other related symptoms of Graves. There is a lot of info on the net if you Google thyroid. Maybe you can print off some info for you family to read to help them understand. Good luck.
