Why im having crave of eatingrawrice
If the craving started recently, it could be due to hormonal changes. I see you are female over 40 years of age. In that case, this could be associated with perimenopause. other causes could be related to anemia and nutritional deficiency.
If it's a long duration complaint, consulting a psychologist might help.
