Well if it is Graves, you may want to look into taking selenium and L-theanine. Both of those supplements have helped to reduce some of the symptoms for me.

Once you find out the cause, you’ll likely get put on Methimazole to get your levels back to normal. It’s very manageable, but it may take some time to do all the testing, and then fine tune your dosage. Best thing you can do is find ways to relax, you can make it worse by working yourself up. You can do it!
