This is the same question you asked yesterday and I responded. The only difference is that now, you've added the vitamin D and ferritin levels.
It's best to keep all of your comments on the same thread, because it gets confusing when you have more than one thread going at the same time, with the same information and we have to keep asking the same questions. Here's a link to your other thread:

As I noted yesterday, antibodies fluctuate and don't have to be tested every time you have other testing done. If you've been positive for antibodies, you should have been diagnosed with Hashimoto's. That's a lifelong disease, for which there is no cure.
With Hashimoto's, the body sees the thyroid as foreign and produces antibodies to destroy it. The disease is progressive, in that, as the antibodies destroy thyroid tissue, the thyroid produces less and less hormones, until, eventually, it produces none.
Your thyroid levels don't really look all that bad, though your FT3 is on the low side. Rule of thumb is for FT4 to be about mid range; yours is at 55%. Rule of thumb for FT3 is upper half to upper third of its range; yours is at 43%. Of course these are, typically, rules of thumb for those on medication so we have something to aim for, but they can also help, prior to medicating, just to see where you're at.
Your vitamin D level is very low; have you been put on supplement for that? Some Vitamin D deficiency symptoms can mimic those of hypothyroidism, so you'll need to get your levels back up.
What's the lab range for your ferritin? Typically, ferritin should be around 70, but reference ranges vary with the lab, so it depends on your lab.
