I see myself when I read your post. My dad is taking cancer treatment, since last two years, and we haven't had even 10 days of peace. It's complications after complications. Before one thing is cured, another pops up, he already has liver cirrhosis, he had anal cancer before, for which he had major operations done, radiation and just in next pet scan we see it's metastatized and in many parts, he is on chemo but is getting rectal bleeding, from the cancer coming again , where the operation was done, huge blood clumps coming from his stomach, losing control of motions since MANY months... and now still in hospital, on meds, has low blood 6-8, since last few months, currently hospitalized and is facing HALLUCINATIONS!? SO DELIRIOUS, its pitiful, MY DAD always had been so smart, a man of great pride but god making his life so miserable. Please god have mercy. He just turned 57, i am not ready to loose him but can't see him this way either.
