Don’t worry.
Christmas will come and go even without your input this year. Your daughter will make sure Evie doesn’t miss out and, relax, it is still 6 weeks away.
One of the most memorable Christmases I had (and not in a bad way) was when Paw had been transferred to London after 4 weeks in hospital up here, a perforated bowel, surgery which went badly and a diagnosis of lymphoma.
Life was pretty sh*t but his course of treatment was decided, D and her BF of the time (now SIL) persuaded to have their Australian holiday after all, where he proposed to her. I simply ignored Christmas preps here, cooked a venison casserole, put the dog in kennels on Christmas Eve and drove to London to camp out in DD3’s flat. On Christmas morning we (other 2DDs , sisters in law and nephew) all went over to the Royal Free with smoked salmon sandwiches for Paw, spent the afternoon with him then went back to the flat for the casserole. On Boxing Day the hospital said he could come home until his chemo was due to start so I brought him back.
No tree, no cards, no turkey, no queuing at the supermarket, no presents, just glad he was alive and that the future although he had no work, no pension and no income was no longer as bleak. That was 2008 - so 11 years ago.
Christmas is not about the ?, ?, ? its having those you love with you. Keep faith that he will be home with you by then
