Hi, your b12 is terribly low & that alone would explain tiredness.
I would suggest that get some good quality multi B & B12 Methylcobalamin supplements, 1-5 mg daily but taken at a differant time than the multi B as they work better that way, eg - say if you take the multi B at breakfast time and then take the B12 lunch time or something similar to that, they both need each other to work better.
I also suggest you have a good look at http://roseannster.googlepages.com/home.
good luck
