To me it seems like she had a severe B12 deficiency, which was most likely due to her being unable to absorb B12 orally, and that she was anemic. The B12 issue was solved with injections, which is unrelated to her diet. She couldn't stomach the two types of non-vegan iron pills she tried, but she still perhaps could have found a (vegan?) supplement she could handle.
Anyway, there are a few comments along the lines of "this has made me question whether I should be a vegan" which seems a huge shame as it seems her main problem had nothing at all to do with veganism.
