Sorry, my response is a bit long.

Thanks for the information. It sucks that you had to go through all that with the thyroid stuff. Hopefully it doesn't take 20 years to figure out my problem; It's been 2 years for mine so far and I'm still in my twenties, so it's kind of difficult to get people to take me seriously (I've been told that I act like an old grandma by some who know me better). (I think there is a delicate balance of passiveness, assertiveness, and how much concern you show when talking to doctors; I initially tried attacking this problem passively with doctors and got told I had an "anxiety" disorder and the doctor wouldn't do any blood tests other than A1C... So, this time, I am being more assertive and laid back in my approach, as in I am only mentioning a few symptoms at a time that I have prioritized along with using logical arguments to rationalize testing to be done, and it's working out better. Yay!)

I just checked and it looks like tests for "T4, FREE" and "TSH" were done. My B12 was checked at the same time, and it was almost 1000 pg/ml which is pretty good I think. I had been self supplementing with B12 for about 2 months up until 1 week before the test was done. It has been roughly almost 3 months since the blood was taken for those tests. I also take a daily multivitamin that has B12 (I have been taking a daily multivitamin for the past 5 or 6 months). So, given that, I cannot be certain about whether I have actually had a problem with B vitamins or not. Ideally, I would just get those checked to compare with last time. I don't want to start self supplementing before getting a blood test again out of fear that if I do, I will never know if low B12 is really part of the problem. It is tempting though! I will be patient.
