So sorry to hear this, Jen.
Your mental health is as important as your physical well being, probably more so if you feel your body is letting you down. I've got no advice except to give yourself permission to enjoy what ever appeals to you. That may not be much, but don't let guilt or anything else get in the way. It sounds like your husband is doing a fantastic job, with someone that caring on your side, I'm sure if there was something you want (or don't want) to do you will get 100% support.
Taxol is a drag, but remember that if something gets too much for you, you can always withdraw. I guess it depends where your head is, you are the only one who can weigh up the equation. Wishing you the best. This is a shit of a disease. Marg xxx
