Your blood test results are somewhat confusing to sort out the cause (s) of anemia from them, not straightforward. Would like to advise to seek an another opinion or see a blood disease specialist.

Most likely, this is iron deficiency anemia, which can also cause a mild of platelets. For degenerative diagnosis and treatment, you need to see a hematologist blood specialist
