Well, this is unfortunate. I think that the things you were eating are going to fall in the line with PICA. This is a disorder sometimes linked to nutritional deficiencies and sometimes linked to psychological issues. Sand is not a food. I don't know what chokepiece is and raw rice doesn't sound tasty. I think first thing is to get your eating in order. Do you work with a physician about this eating issue? Do you have a diagnosis? With regards to your face being fat, I must say, we have genetics to live with. And I have to wonder about body dysphoric syndrome in which you have an odd image of your body/face. Women with anorexia have this. So, this is confusing but I think you must first have a healthy lifestyle and second learn to be accepting of who you are. If you were purposely eating sand and raw rice to be thin, that is problematic. Let us know more so we can try to help.
