Based on high TSH and extremely deficient FT4, you're very hypothyroid and need replacement hormone. Is that total T3 or free T3? (You must add the lab range for each test when you post results.) Can't interpret that level without the range. But it doesn't matter too much. You're still very hypothyroid. The thyroid antibody result pinpoints the cause for your disorder as autoimmune. Have you been prescribed some hormone yet?
That nodule is very large and must be biopsied. Has that been scheduled? I'll let someone else comment further on that, since I have no experience with nodules myself.
