Andi, I know you've posted your supplement list before, but if you would be kind enough to do it again, I'd like to look at it. I'd also like to know precisely which antibodies were tested. See the table on this page:

Can you look at your labs and see if TPO and thyroglobulin were also tested?
It could very well be that some of your supplements are suppressing your TSH (been there, done that), which might explain why your FT4 is pathetically low. Hyperthyroid? More like hypo, although I'd really like to see the T3. Yeesh. Your endo is a nut case.
Note that hypertension can be a symptom of hypothyroidism. Mine goes the other way--I have low blood pressure that gets lower as I get more hypo--but most people are not like me in that regard.
You need to lower the selenium asap. Way too much, and it's clearly not doing anything for your nodules.
The only other thing I'd suggest at the moment is that if you're willing to drive 3 hours, there's a wonderful endo in Lake Mary. Until I found my current endo here in New Jersey, I seriously considered flying back and forth to Florida to continue seeing her rather than settling for substandard care. Luckily, I found a good endo who is closer, but I still miss Dr. Ansara. She's just amazing (and she also has hypothyroidism, so she's more sympathetic that an endo who is not similarly afflicted).
