Help? Ampullary/duodenum

Hi hubby recently diagnosed and underwent a large surgery PPPD / whipple in July 

he is on second 0f 8 rounds of oxaliplatin and capecitabine.

can anyone give me any advise on any of the above .to be honest we are so shellshocked we don t want to know about any of it . The oncologist mentioned 5/24 nodes removed and RO margins .

chemo is horrid and can anyone advise on something for anxiety which my hubby is suffering from and gets worse when we go for treatment . Thank you
