not being able to eat even a week after blacking out

about a week ago, i blacked out to the point i was paralyzed and completely unconscious and throwing up for hours. ever since, i havent had an appetite to eat, and anytime i do eat, i feel nauseous. ive been eating very little to completely nothing a day. today i only had a muffin, and yesterday i only had a salad. its been like this for a week now. is this normal? how do i get better?
