Hello~
This is awful, is there anyway you can see another doctor? If you can, please do ASAP, have another blood series drawn and demand answers and help. I am so sorry you are going through this.
That's criminal they aren't helping you. I had a blood transfusion when my hemoglobin was at 7.9. They never cared about my ferritin, which made me mad because you can have normal hemoglobin and low ferritin. I had to supplement with iron pills.
You need to switch doctors.
Can you get someone/an ambulance to take you to the hospital for an emergency iron infusion?
Have you looked into pernicious anemia?
Do you also have issues with Vitamin B12 levels?
