Hi Tarajp123 Your FT4 and FT3 are too low. FT4 should be in the top third of the range (19+) and yours is 39% through range. FT3 should be in the top quarter of range (5.75+) and yours is 36% through range. Your conversion is OK at 3.5:1 (good conversion takes place at 4:1 or less). You need an increase in your levo despite your TSH being low. Unfortunately most doctors tend to dose by TSH.
Dr Toft, past president of the British Thyroid Association and leading endocrinologist, wrote this in an article in Pulse Online magazine:
"The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range - 0.2-0.5mU/l.
In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l. Most patients will feel well in that circumstance.
But some need a higher dose of levothyroxine to suppress serum TSH and then the serum-free T4 concentration will be elevated at around 24-28pmol/l.
This 'exogenous subclinical hyperthyroidism' is not dangerous as long as serum T3 is unequivocally normal – that is, serum total around T3 1.7nmol/l (reference range 1.0-2.2nmol/l)."

Your vitamins and minerals aren't at optimal levels, they need to be optimal for thyroid hormone to work properly.
Vit D should be 100+ so you could supplement with 5000iu D3 on alternate days, or 2000iu daily, for now to bring that up. When taking D3 we need to take K2-MK7. Vit D aids absorption of calcium and K2 directs the calcium to bones and teeth rather than arteries and soft tissues. Take K2 at a different time of day to the D3, and take both with some dietary fat.
Your B12 is too low. The Pernicious Anaemia Society recommends 1000. You can supplement with Jarrows or Solgar sublingual methylcobalamin lozenges, 5000mcg to start and later reduce to 1000mcg. When taking B12 we should also take a B complex to balance the B vits. Thorne Basic B and Jarrow B Right are both good ones and contain methylfolate which will help improve your folate level (but it's difficult to know how that falls within the range as it hasn't been provided).
I'm afraid I can't help with cortisol as I don't know that test.
