ANAEMIA and HAEMOCHROMATOSIS

Question: How is it possible that I was severely anaemic, but now have hemochromatosis? (I can’t find anything about it online.)

Background: 2 1/2 years ago I was diagnosed with severe anemia where my ferritin level was 10 (was told it should be around 120 and that under 30 means bad physical effects). Several months after stopping the supplements my was at 180ish, my doctor brushed it off as she wanted to see if it would go down over time.
So now, around 1 1/2 years after stopping the supplements, my iron is the same and i have just been diagnosed with hemochromatosis.

Relevant GENOTYPES: All of these are part of the HFE gene and have the variations.
rs1800562 AA (the highest risk hemochromatosis genes on HFE)
rs1572982 GG
rs2794719 GG
