Lillie,
My Mom was also diagnosed w/ Stage IV adenocarcinoma in March. She is so young and so healthy so iit was really hard to deal with. At first I was doom and gloom and could think nothing but negative thoughts. I realize now (after reading about people on this site and others) that miracles happen and she may live a lot longer than I thought. (My mom met a lady the other day that has lived 9 years after being diagnosed w/ stage IV) She has tolerated chemo very well so far. I hope that your father starts to feel better soon and try to stay positive! Best of luck with the wedding
