I'm not sure about the other tests but your Free T4 (FT4) is BELOW range and your Free T3 (FT3) is below mid range.
many people have found that in order to feel well they need their FT4 to be MIDDLE of the range if not a bit higher AND (that means in addition to) their FT3 to be in the UPPER 1/3 of the range.
Thus if you are feeling hypo (low) thyroid symptoms I would not be surprised because you are below those levels. Some people feel fine with your numbers but many don't.
TSH is a screening tool at best and is not that reliable. But it also would indicate borderline hypo as the American Academy of Clinical Endocrinologists (AACE) recommends a reference range or (0.3 - 3.0) your result of 2.7 is towards the upper part of that range for what it's worth.
Vitamin D is also very low.
Many people find that they need to be towards the upper end of the ranges for both Vit D as well as Vit B-12.
