What has recently happened to me

I have puked three times today and I hate doing it after eating. It's getting worse, I suppose. For the first times, it happened after I had eaten too much. Gradually, it happened after I had eaten my normal ration. 

Recently, it happens everytime after I ate. Many attempts to prevent it to happen have been done but none of them helps. It just happens automatically like my body hates any caloric intake coming through my mouth. I guess it starts to hate anything that goes into it. I don't know how long it's going to happen but I guess there's nothing I can really do.

I vomit everywhere, everytime after eating. I hate it when I have to sneak to the toilet and make false excuses afterward. However, I guess it's better than vomitting in public.
