Had review on 12 Septmber as 50mcgs Thyroxine was too high giving me palpitations and chest pains, had ECG which came back ok. Dr decided to keep me off Levo until symptoms worsened as I was borderline being hypothyroid and this is why I had such bad side effects. Have been feeling ok trying to keep active and eating as well as I can including taking fish oils, vitamin B and Selenium/zinc supplements. Gradually I have been feeling unwell with original symptoms coming back so 23 September decided to put myself back on 25mcgs, only second day in but depression in mornings is chronic. I was some months ago on Sertraline but decided I wanted to come off them slowly and see if I can sort out this thyroid problem first. Do you think depression is due to thyroid or something else and should I go back on antidepressants, can't keep feeling this way🙁 Did ask again to make sure all tests were done and that they were normal with the exception of Vit D test which wasn't done but my kidney function was good so he thought it was ok.
