Oh, pity Endocrinology are not going to review you.
If you didn't need Thyroxine then yes it could make matters worse but your 2.5 June TSH (on Thyroxine ?4 months) didn't indicate you had had no need of it. If the Thyroxine were more than you needed at that time your TSH would have been suppressed.
Do you have any symptoms of over-treatment other than anxiety - eg feeling permanently too hot for the conditions (I know flushing & night sweats can make it hard to tell), weight loss, diarrhoea, fast heart/pulse rate? If so I would alert your GP as they may want to repeat the TFT sooner rather than, later.
On the other hand, if you are hypothyroid & on oral oestrogen that will probably affect your thyroid status, increasing your requirement for Thyroxine.
"Good levels" of sex hormones & those related to them, such as FSH & LH found on testing at around menopausal age would not necessarily indicate you are not menopausal. It's a potentially very unreliable snapshot during a time of great hormonal fluctuation, which is why they prefer not to test. But you are not going mad. Or if you are, you are in good company here!
