Serious anemia scare

Ok so I’ve always been anemic but where i come from it is not considered an illness of an important kind, just like eat more greens you’ll be fine kind of a thing. In my case it is hereditary as some doctors have pointed out in the past. However, recently I started experiencing heart palpitations, dizziness and would sleep a lot and naturally got scared and went to see the doctor. They did my blood test and the results were horrible to say at least. Iron level 24... minimum should be 50. Hemoglobin way under too. I keep reading all this can cause even a heart attack in the future. Please tell me what to do, any super foods that help big time and fast? I already changed my diet and bought all of the iron rich foods as a sort of a start.
