Looking at your results you haven't shown the lab ranges (the figures in brackets next to the result) I'm not surprised you don't feel good.
You seem to have gone from 8.03 to 1.53 to 3.88 in three months. Is your T4 15.1 or 151 - hope it is 15.1! ( have just read on through your posts and it is)
I'm not great at interpreting results only my own really. I wouldn't feel good at 3.88 and When I was being treated for Graves Disease (hyper with antibodies) I became hypo, my TSH went up to 7.8 (0.5-5.5) I felt dreadful so I don't think having tur TSH leaping about makes you feel good (I'm not medically qualified, I just know I didn't feel at all good when that happened to me)
I take Jarrows sublingual B12 - you can buy them on Amazon. They will boost your B12 quite quickly - my B12 was similar to yours and went up quite quickly once I took the Jarrows. I think I get 5000mcg ones - they're the cranberry flavoured ones.
Make sure to check the label and buy methylcobalamin NOT cyanocobalamin if B12 looks to be a bargain price then they are probably cyanocobalamin so avoid them.
Hope you feel a bit better soon.
