Thank for asking to HCM
I can understand this, your tiredness
is not because of the thyroid dysfunction
but this could be functional one and no need to worry about this you have to keep continue then thyroid medicine that you are taking, for the problem that you have you need to low down your stress
level very low in my opinion its better to try "Tab Chlorodiazepoxide" three times in day every thing will be fine, hope this information helps you have nice day.
