I'm sorry you're feeling that poorly.
is there a way to have your FT4 and FT3 tested too? (if need be at own expense or at another doctor?) I don't know how things work over there in that regard, but you wont get your levels optimalised without those.
TSH alone does not give sufficient information, even more so since the intake of T3 (armour contains both) is a known TSH suppressant.
a disbalance between FT4 and FT3 which is not uncommon with Armour, can cause symptoms too.
point is I really think you need those in order to know where you're add and make the proper dosing adjustments.
Symptoms can be deceiving to go by.
