Hi here are my test results. I am very worried about my symptoms which are affecting my quality of life - depression, anxiety, unable to think straight, tearfulness, constipation, joint aches, heavy periods, irregular periods, loss of appetite, dry skin, cold intolerance. Latest results below I have been told are normal so what is wrong with me I don't understand. I take 50mcg Levothyroxine for hypothyroid diagnosed in 2011. Anything further I can provide please let me know, thank you.
