So I've always had issues with eating. For a long time I would be able to eat heaps of food and be fine. I wouldn't feel sick and i wouldn't be like guilty i guess. but for the past couple months since about January. I have been having bad issues with eating, I would feel very sick and nauseated and sometimes painful when I would eat food. so I started to eat less. But for the past 5 or 6 days I feel almost guilty. I havent been able to get myself to eat anything. I've barley drank any water too. I'm just not really sure what's going on. any help would be appreciated
