Hi! 

My husband has been diagnosed with it on 31.5. He was told pretty much the same thing as you. 

He was first given chemo radiation (27 fractions of radiation and capecitabine tablets to take on radiation days). We have 7 left.

After wards a 6 week break till surgery - with 2 cycles of CapeOx  chemo. 

He has a lot of mood swings. Sometimes super positive sometimes dreading the stoma, sometimes believing he won't need surgery then again resigning to it. 

We talk as much as possible to help him cope. He reads especially on stoicism , meditate a bit, and he gets super miserable if for whatever reason he doesn't go at least for a walk. That halps him a lot. Try to stay active and engaged. 

Good luck!
