5 years ago (aged 17) I was dealing with a lot of stress but didn’t do anything about it. I was anxious and continually exhausted and my mood was very low. After seeing my GP and having bloods taken I was diagnsoned with an under active thyroid and started on Levothyroxine. A few months later I was also diagnosed with Depression and Anxiety and started on an antidepressant, Sertraline. I have been having 3-6 monthly blood tests for my TSH level and each time my dose of thyroxine is changed. At one point my TSH level was 22 and at another point it was 0.03 - at this point, 2 years into taking thyroxine my GP said perhaps I hadn’t got an underactive thyroid maybe it was linked to a viral illness at the time. However, 6 months later another test, showing I was underactive again! When the GP says I am not taking enough thyroxine I don’t have any symptoms, when the GP increases my dose I feel dreadful. I have asked for an endocrinologist referral but my GP is reluctant. Anyone been in a similar situation at a similar age?
