I recently recovered from food poisoning, but now i am feeling depressed, i have 0 appetite most of the time, and when i do eat, i feel a mental urge to barf, i have been to wright patt & soin er who found nothing physically wrong, what should i do?

It is not feasible to provide an opinion without additional history, physical examination may be some tests. It would be prudent to see your doctor to see if you may have depression. Depression is treatable. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Drink more water. Wish you good health
