Hi, Every Time I Eat (anything) I Get A Nausea

Hi, every time I eat (anything) I get a nausea feeling with extreme bloating in my upper stomach/chest region. Along with a very uncomfortable tightness and pressure. It feel like the symptoms I had before I had my gallbladder removed. I can hardly eat much. Breakfast is my best meal and from them on anything I eat causes this feeling. Plus I look like I swallowed a watermelon. Very uncomfortable mainly on the right side.
