Dfriend will be spending Christmas alone, she does every year and I always ask her to ours. This year I'm quite worried about her as I think she might be depressed and she said the other day she felt quite sad about another Christmas alone so I said (again) well come to ours then but she said no thanks 
I know I can't force her but AIBU to think it would be better for her to be with friends than wallowing in sadness??
