While out with people, what can be less invasive are musical concerts in churches or concert venues (churches better for your situation as colder so less comfortable and often less full, or midweek lunchtime concerts in concert venues) …but many choirs and musical groups come together to play lots of the beautiful music of Christmas.
if you are up to it, that could be really lovely for you. But also, many of those concerts are relatively cheap…so less need to feel guilty if you can’t go on the day.
What foods are you enjoying now? As I know for some, their tastebuds change during treatment or there can be some foods not allowed. If you loved the full turkey experience, get a turkey breast to roast and maybe get everything preprepared to just slide in and cook. Or plan a couple of favourite sides to do (together if you are up to it).
Also think about what easy foods you like to snack on, to graze during the season, or if you are having a Victorian consumptive lady day - do you love sausage rolls (and are there particular brands, or using your butcher’s sausage meat..but ready rolled pastry this year…)? Are you a hummus and breadsticks and olives pair? Do you like a good cheeseboard? Do you love 15 tubs of Quality street (or a nice box of Leonidas chocs)? Make a list of the things you both love that are easy for grazing to get in.
Between rounds 3 and 5, will there be a day or two that you might feel energized? And might make a favourite lasagna (well 2, as 1 is to freeze), or curry, or casserole/stew…? Just to have a couple of your favourite meals in the freezer that can be easily taken out and reheated or baked without much effort over the season.
And maybe think about what would make either a consumptive Victorian lady day, or just a nice relaxed day of you and DP, look cosy. Do you have a cosy throw/soft blanket to snuggle under, and enough cushions of different shapes sizes to make the couch comfy? Are there particular smells you love, that could be in reed diffusers or nice candles? Do you have an open fire/solid fuel stove? Even if you don’t normally use it, can you get the chimney swept and have some wood/fuel in to be able to light it for a cosy day at home? And what about lighting? Does your relaxation room (I assume the sitting room) have nice soft lighting conducive to relaxing or just a central ceiling spot? Can you get a couple of side lamps or some fairy lights to twine around the place (Some are very discrete and battery operated) to soften the glow. And is there 1 corner with a comfy chair and good lighting for reading, if you might like to do that (or some crafting)?
And do you have some nice bathing products to look after yourself and your body as it goes through its internal war? Comforting smells, nourishing body lotions, soft sponge etc?
Sorry, they’re all a bit random. But I hope they help the thinking process. And good luck with the treatment.
