I don't think you're having issues converting, Nancy, both your FT4 and FT3 are at a similar point w/in the range. Typically if you're having that problem your FT4 will be high and your FT3 will be much lower, relatively speaking. I do think your numbers will be lower this time out though.
TSH responds primarily to T4 levels especially before we begin treatment. However meds that contain T3 (Cytomel, Thyrolar, Armour, Thyroid) tend to drive down TSH (and often FT4). In your case I believe your TSH is slightly high (2.0) because you'd feel better with a little more FT4 / FT3 in your body.
Have you had your ferritin checked? Often low iron can mimic hypoT symptoms, and being hypoT can also cause low iron.
I think I asked already, but what supplements are you taking? Are you taking Vit D, selenium, Vit E and magnesium? These are key thyroid supplements that we should all be taking. B12 is another good one - but most of us don't take anywhere near enough. I was told 3000mcgs a day, sublingual, by a biochemist to ensure 1% absorption.
OK, I think you edited a post to include your your supplement info - editing doesn't make a post show up as 'new' so I missed it until now.

I'd get my Ferritin checked; you might need some iron. Although the best way to get it is to eat more liver / red meat (liver extracts can help as well, I believe).
Add in the selenium (200mcgs for a few months since you've not been getting any for a while now, then 100mcgs thereafter), Vit D (be sure it's D3) 400 -800 IU, Magensium 600mgs (divided doses), Vit E 400-800 I.U. and B12, 1000-3000 mcgs.
I suspect that the selenium and Vit D will really help you feel better. You can't use thyroid hormones well w/o vit D and most of us LCers don't get enough - although you do live in CA so getting tested might be a good idea. Although you can supplement with 1000 IUs of Vit D3 safely.
