I used to feel exhausted all the time, and a doctor I consulted told me to get my
thyroid tested. My
TSH was 7.9 and I was put on levothyroxine 12.5. This was a year ago.
Recently, I am facing similar symptoms. I am tired all the time. I lack focus, and I can't work. I thought it was my thyroid, but my TSH is 3.7. I have had everything tested, such as cortisol and
vitamin d, but everything seems normal. I don't understand why I'm so exhausted all the time.
