My stomach has been hurting really bad for the last week. It feels like im hunger pains and it wakes me at nite I vomit and I don't even b full.

See your doctor. Pain in the abdomen can be caused by many things. Most of time it is not serious but it can be very difficult to find out what is wrong. I recommend seeing a doctor. Your doctor will need much more detailed information and a physicial exam to give you an answer.
