@ddon This bit is the very scary time, hang on there and once you get a bit further, know your full pathology and have started treatment it does get easier, you will feel normal again, even during chemo. I am nearly out the other side but I remember the terrible fear at the start.
That's great your husband is such a great strength, I am lucky that mine was too. We walked every day after diagnosis and it helped us talk our way through it and the exercise was great to keep my body strong for surgery, chemo and now radiation.
The port is a great thing to have, I just had mine out but was grateful I did it.
I had twin sons going through HSC this year too and a daughter finishing Uni. And we survived it! Made us closer if anything and it was good for me to have someone else to focus on.
There is lots of advice here for the practical stuff once you are on the road but I am sending you my thoughts and wishing you the smoothest path through. Good luck with it.
