Is it true or not that we are drawing near to the end?

I'm new to this yet I want somebody to either console me that things could improve or now is the right time to plan for losing my better half. My significant other was analyzed on March 5, 2018 with stage 3 rectal disease and he did radiatin and chemo before medical procedure to eliminate rectal cancer and lymph hubs. Medical procedure was in August and the specialist tracked down a spot on his liver during medical procedure and chose to biopsy and it was malignant growth. Completed a half year of chemo and liver oncologist persuaded us that every one of the cancers in his liver were situated on the right side and he could do a liver resection and eliminate every one of the growths. Medical procedure was in June 2019 and my better half's liver didn't begin working right away so we verge on losing him then. Did a PET output in November and malignant growth was in his liver and had moved into his lungs. We did 6 additional long stretches of chemo and PET sweep in May 2020 showed fantastic reaction to chemo and no dynamic cells. We had a great summer. Next PET output was planned for November 2020 and filling again in his liver and lungs and presently situated in the lymph hubs of his shoulder and chest. Begun chemo again and after 1 round our oncologist quit her work on passing on us to track down another oncologist. New oncologist needed to change him to chemo pills and evastin mixtures and following multi month on the pills and evastin CEA was expanding and the specialist booked a CT and uncovered pills were not working. So back to mixtures and on the day he was assume to begin new routine his bilirubin was 15.1 so he was owned up to the emergency clinic and the following day they put a stent in his liver. The next week bilirubin was going down and chose to do a series of chmo 2 days after the fact and 3 days after chemo we needed to go to trauma center since he was having horrendous stomach torments and he was becoming more yellow. He was owned up to the emergency clinic and presently his bilirubin was 16.2 and that was in May and he has been declining from that point forward. They had the option to put a biliary channel and complete 3 rounds of chemo since. Bilirubin is down finally check to 1.7 however the biliary channel has been a bad dream. Indeed it is working yet they just swapped it for the third time today. He was assume to do one more round of chemo tomorrow yet he said it is absolutely impossible that he can do it tomorrow. He weighed 190 lbs in January of this current year and today he weighed 158 lbs. furthermore, when he plunks down now he falls asleep. My significant other doesn't allow our oncologist to discuss not too far off he simply needs to realize what should be possible today and our oncologist regards that. I feel like I'm on a passionate rollercoaster. I don't have the foggiest idea how to feel any longer. I'm an instructor and I'm assume to return to school in about fourteen days and I couldn't say whether I ought to. I just lost my father March twentieth from malignant growth and I see my better half encountering a portion of exactly the same things my father did toward the end yet perhaps I'm simply neurotic. I'm trusting somebody has had a comparable encounter and can give me an understanding to what's straightaway.
