I suffer from loss of appetite, feeling of fullness, vomiting ?

I suffer from loss of appetite, feeling of fullness, vomiting, diarrhea (sometimes bloody), fatigue, abdominal pain, cramping, frequent urge to have a bowel movement. I went the emergency room, had an ultrasound and they found 3 black spots on my liver? What should I do next?
