Everytime I eat I feel sick. Normally its during school but it happens at home too. This past week and a half or so I always feel sick after I eat. Sometimes I get hot flashes and feel like I could pass out and throw up.

Since . Since this has only been going on for about a week or so we can assume that you may have a mild case of stomach flu (gastroenteritis). Usually this goes away within 7-14 days. Drink plenty of water and eat a bland diet. On the other hand more serious issues like blood glucose abnormalities (too high or low) could be a factor, anemia, dehydration, pregnancy, etc. Therefore it is a good idea to go see a doctor for a complete evaluation/testing in case there is something more serious than stomach flu going on. Best of luck.
