How does anyone handle the fear?

Over the course of 5 weeks my husband has started having daily bouts of diarrhea, a stomachache, then yellow eyes and now yellow skin...waiting for CT scan but finding it so difficult to function everyday just doing normal life is hard. I want to be positive and supportive but don’t know how. Hard to try to have normal conversation it’s like the elephant in the room and I don’t want him to know how terrified I am that this is something bad. Do these symptoms always mean pancreatic cancer or can they be a result of other conditions? Thank you
