Just diagnosed: Surgery not an option, looking for hope

Went in for my first colonoscopy in December, F age 58. Had negative Cologuards for the last 4 or 5 years. My PCP gave me a FIT test in September which came back positive. Colonoscopy revealed a rectal mass (close to the sigmoid colon junction) she said was typical cancer presentation. Had some abdominal pain and went to ER. PET scan found mets to liver and both lungs, stage IV. Colorectal surgeon told me that surgery, "would not benefit me." Oncologist gave me 2 to 3 years prognosis, said treatment would be palliative and not curative, and surgery, "would never be an option." Started FOLFOX + Mvasi in January; just finished my 2nd round. CEA was initially 58, and is now 46, so that is good news I think. Don't really have a question, just looking for some hope from the stories of other people.
