I Had Thyroid Goiters Several Years Ago And My Thyroid

I had thyroid goiters several years ago and my thyroid was removed. I've been on Levonthyroixid since then but continue to be fatigued w/brain fog, anxiety, etc...I want to go on Armour thyroid but my Endocrinologist refuses. I'm tired of just surviving with no joy in my life or the energy to enjoy my life...what do I do
