"Big words" is not a good way to describe your anemia, given the myriad of kinds there are of it involving big words, but suffice it to say that:
your body either isn't making red blood cells fast enough to replace the dying/dead ones,
or it is losing too many too fast to replace them,
or you are bleeding from somewhere (probably not, that would be obvious),
or your blood cells have deficient iron/hemoglobin.
What can you do about this? well given many of the causes of this are hereditary, the best you can do is increase your intake of iron, vitamin B12, and folic acid.
so eat red meats and fish, or take some supplements. you did always look anemic in your pics, so this isnt a surprise to me.
