How do you cope when colon cancer becomes incurable?

I’m 62yo and was just told that my colon cancer has become incurable. Statistically I have 2 years, with treatment but the treatment will just prolong the inevitable. My husband and I are in shock and don’t know what to do. This is not what we expected 2 years ago when I was diagnosed with stage 3 CRC. I went through surgery and 6 months of chemo, which ended in 2 weeks in hospital on IV nutrition due to chemo toxicity. At that time they said I was likely cured. 9 months later I had a liver lesion (so now stage 4). I had that removed at the end of Jan 2026 but a new lesion 5 months later with evidence of more spread outside the liver. I’m devastated. I have an adult disabled son who lives with us. I can’t image leaving my husband and son alone. Alls I can do is cry.
