I've recently been diagnosed with Graves (auto immune hyper thyroid) although waiting for the results of antibody tests to confirm this. I started carbimazole just under a month ago and feel loads better. Symptoms palpitations, shakes, anxiety, feeling generally yuk, no energy, not sleeping, emotional roller coaster. I also have been having an aching sore throat on and off for a good few months bit didn't relate this until after diagnosis. They all came on at different times so didn't put them all together though. My gp thought I had depression/anxiety.
My bloods Tsh 0.01, ft3 23.4 (2.8-7.1), ft4 54 (10-23). I've also got a borderline b12 of 189 (180-1000) so have started self treating with supplements after seeing lots of posts on here about B12. If you have mild thyroid eye disease they recommend to start selenium supplements 100mcg twice a day, I started these before I saw endo but didn't see the eye disease myself, it was others who noticed it so might be worth asking family if your eyes look different to normal.
You may or may not have the same thing as me, either way hang on in there, try and rest and look after yourself. I find caffeine makes my symptoms worse as does being stressed/upset and rushing around doing too much. If you get other troubling symptoms before you see the endo ask you go to treat them-the worst they can do is say no. I started calcium channel blockers for the palpitations and they've made a big difference. Hopefully you'll get a diagnosis soon and start treatment. All the best.
