All the advice you have gotten is great - so good in fact that it leaves me little to add except to reinforce that your feelings are not odd or abnormal. Christmas is exceptionally tough on us oral cancer patients.
You will love Italy when you go - I wish my mother-in-law had offered to pay for us ;)- but I went in between cancer occurrences and found the pasta just the right texture to eat.
We just scheduled down times at cafe's in the plazas (in Rome) or on the canals (in Venice) to accomodate my lack of energy.
