How about lighting some Christmas scented candles or having some Christmas scented diffuser's around the house,cinnamon,nutmeg,ginger and orange always remind me of Christmas and you can pick them up really cheaply.
You could pick one afternoon to have a Christmas movie session with your DC,there are lots on the tv at the moment if you have sky,if not Poundland are selling some Christmas dvd's or you can pick them up for a couple of pounds in the supermarket.
We do a couple of Christmas movie sessions with our DC,we turn the big lights of and have the Christmas lights on,we pick a movie and I make treaty snacks to have whilst we watch the movie,things like flavoured popcorn(you can pick up Christmassy one's now)Christmas cookies(again you can pick them up cheaply or make them)mine love chocolate and orange or stain glass window biscuits and peppemint chocolate bark is really easy to make or you could make hot chocolate fudge sundaes, you can have flavoured hot chocolate or soda floats.Something that feels and tastes Christmas inspired and is a real treat for the children.
I don't know how old your DC are but if the right age you could take them to see santa and then after take them to get some luxuary hot chocolate from a coffee shop.
Something we've done for years now with our 5DC is we take them out in the car to drive around and see all of the beautiful Christmas lights(there are some amazing displays about 20 minutes drive from where we live)we have warm throws in the car for our children to have over they're legs and I make them all a luxuary hot chocolate to have in they're travel mugs and I take a little tub with some warm mince pies and chocolate cake in and it's something they all still look forward to and it's almost free to do.
When we have a dry day we also go for a drive out into the countryside and we collect some greenery,berries and fir cones(to bring home so we can make displays with them)and I pack a hot picnic for us to have in the car before we come back home.
Again the only thing it costs us is a couple of pounds for the petrol.
Have a look online as well Christmas2018 there could be free events where you live,where we live there are usually free Christmas carols held at lots of the churches where we live and some of the charitys and community centers have Christmas things you can go along to and most of those are free.
I hope you start feeling better soon and that you find your love of Christmas again very soon [santa]
