i have never enjoyed christmas even as a child, i did all the right things when i had my little boy....he is 38 now, we went to the family gathering week before christmas but always spent christmas at home (just the 3 of us) and i served a buffet, i now spend christmas the way i want, lost my husband when i was 39, i have explained to my son that i am happy to spend christmas on my own and he accepts it. you should talk to your daughter and tell her how you feel, that the pain is dreadful and doing all the cooking is not something you can manage anymore, it might be that she feels she has to come to you so you are not alone with your son, with the covid19 ,,,would it be safe for her to visit?,,,please just talk to her and enjoy christmas the way you want to xx
