I Am Female With A History Of Type 2 Diabetes.

I am female with a history of type 2 Diabetes. I am currently suffering with a distended belly and rapid weight gain (pound a day). An ultra sound found fluid around my liver. I am a non drinker. When I cough it hurts my upper belly. I have had a cold and I am exhausted. What diet or exercise can I do to eliminate this water around my liver (if that is what is causing my discomfort)?
