Are you really 21 years old with 320 ng/dL total T?
Nutritionist? what for?
You were were border line anemic, if thats from your nutrition I dont know, full medical assessment is required, hard to do it from a forum, but dont think a nutritionist is the best option.
Take new bloodwork when you are eating and living healthy, without being on stupid keto. Dont forget LH and FSH. For thyroid do TSH, FT3 and FT4. Also b12.
