Do ask for your B12 result and range! With all those other results I would be surprised if you are not deficit. As said above, go onto the PA forum for more info.
You must be feeling terrible with those numbers!
I know that dr's like to wait 6 weeks to see if the new blood cells are better than the old - but still!
I think you need to be doing lots of research into thyroid and B12 because you are going to need to know how to get the right treatment/tests. Good starters are Stop the Thyroid Madness and B12 deficiency websites. Could it be B12 book by Sally Pacholok is great. Ask doctor for intrinsic factor test - 50% wrong if you haven't got but still should be done - if comes back showing IF then this is accurate.
No reason not to start supplementing Vitamin D - by sun is best - should be starting to get some beneficial rays now. Otherwise, softgels or liquid, start on 5000iu daily for week then up to 10,000. K2 everyday too - it puts the vit D into the bones. Magnesium in different forms (not oxide) and baths/foot soaks in epsom salts. Once you get lots of sunshine though, drop the supplements right down, or stop until have test to see where you are. Difficult to reach toxicity with vit D but it is possible. Aim for about 100 in range.
Ferritin should be around 70 and folate i've heard said about 10-15. B12 needs both of these to do it's job. I know little of how to raise ferritin/iron as mine is generally high. There is debate as to which is better for you - folic acid or folate. Folate should be but some people may be sensitive to it so watch for that.
If your doctors won't do full panel of thyroid tests - including FT3, reverse T3 and anti bodies - there are private tests you can have done.
Also with B12 - methylmalonic acid (mma) and homocysteine (HCY) are better tests to determine if B12 low at cellular level. Both can be done at surgery but may not be done.
Also, if going down private road, look at having saliva adrenal tests.
Remember, any supplementation before testing will skew results.
