Hi there ~ I understand your concerns. I hope you are getting your anemia treated with the right iron supplementation. They are available over the counter in grocery stores. However, you may be covered with your insurance if you are prescribed these medications from a doctor. I do not think that the dark circles are a major concern and they usually get better with your hemoglobin levels, rest and less anxiety. I am sure you have anxiety about your height, however you still have some more time before you attain your adult height. I hope this information helps relieve you anxiety about your height. Take care and please consult a psychiatrist if these suggestions are not helping. Have a lovely day!
